  • 2 8 V < VSINT,func < 40 V: Device will still be functional including the state machine; the specified electrical characteristics might not be ensured anymore. The VCC1 is working properly, however, a thermal shutdown might occur due to high power dissipation. The specified SPI communication speed is ensured; the absolute maximum ratings are not violated, however the device is not intended for continuous operation of VSINT > 28 V and a thermal shutdown might occur due to high power dissipation. The device operation at high junction temperatures for long periods might reduce the operating life time.
  • VPOR,f < VSINT < 5.5 V (given the fact that the device was powered up correctly before with VSINT > 5.5 V): Device will still be functional; the specified electrical characteristics might not be ensured anymore: – A reset could be triggered de pending on the Vrthx settings. – The specified SPI commun ication speed is ensured. Note: VS,UV < VS < 6.0 V: the charge pump might be deactivated due to a charge pump undervoltage detection, resulting in a turn-off of the external MOSFETs.

5 System Features

This chapter describes the system features and behavior of the TLE9185QX:

  • State machine
  • Device configuration
  • State machine modes and mode transitions
  • Wake-up features such as cyclic wake

5.1 Short State Machine Description

The BLDC Driver offers six operating modes:

  • Init Mode: Power-up of the device and after a soft reset.
  • Normal Mode: The main operating mode of the device.
  • Stop Mode: The first-level power saving mode with the main voltage regulator VCC1 enabled.
  • Sleep Mode: The second-level power saving mode with VCC1 disabled.
  • Restart Mode: An intermediate mode after a wake event from Sleep Mode or Fail-Safe Mode or after a failure (e.g. WD failure, VCC1 under voltage reset).
  • Fail-Safe Mode: A safe-state mode after critical fail ures (e.g. Temperature shutdown) to bring the system into a safe state and to ensure a proper restart of the system. A special mode, called Software Development Mode, is available during software development or debugging of the system. All above mentioned operating modes can be accessed in this mode. However, the watchdog is still running. Watchdog failures are indicated over INTN pin instead. However, the watchdog reset signaling can be reactivated ag ain in Software Development Mode. The Watchdog will start always with the Long Open Windows (t_low). The BLDC Driver is controlled vi a a 32-bit SPI interface (refer to Chapter 11 for detailed information). The configuration as well as the diagnosis is handled via the SPI. The device offers various supervision features to support functional safety requirements. Refer to Chapter 10 for more information.

Datasheet 17 Rev. 1.0 2021-01-21

5.2 Device Configuration

Two features on the BLDC Driver can be configured by hardware:

  • The selection of the normal device operation or the Software Development Mode.
  • Enabling/disabling the CRC on the SPI interface. The configurations are done monitoring the follow pins:
  • I N T N / T E S T
  • P W M 1 / C R C The hardware configuration can be done typically at device power-up, where the device is in Init Mode or (only in case of CRC setting) in Restart Mode. Software development Mode configuration detail After the RSTN is released, the INTN/TEST pin is internally pulled HIGH with a weak pull-up resistor. Therefore the default configuration is the device in normal operation. In order to configure the Software Development Mode, the following conditions have to be fulfilled:
  • Init Mode from power-up
  • VCC1>Vrtx
  • POR=1
  • R S T N = H I G H The Software Development Mode is configured using the following scheme:
  • Only one external pull-down on INTN/TEST pin follow ed by an arbitrary SPI command, the device latches the Software Development Mode.
  • External pull-up or no pull-do wn on INTN/TEST pin enable the device in normal operation.
  • To enter Software Development Mode, a pull-down resistor to GND might be used. Figure 3 Software Development Mode Selection Timing Intn_filt is a filtered signal from INTN/TEST, with the filter time t SMD_F (P_11.2.7). Intn_filt starts (at the rising edge if RSNT) wit the value 1. The INTN/TEST is externally pulled-down Soft. Dev. Mode OFF for tSDM_F to avoid supply glitches Soft. Dev. Mode ON LATCHED (first SPI frame) Init Mode Normal Mode Successful latched Software Development Mode Time/us tSDM_FIntn_filt Mode RSTN INTN/TEST Intn_filt: internal filtered INTN/TEST signal Entry in Software Development Mode (not latched )

Datasheet 18 Rev. 1.0 2021-01-21 Note: If during monitoring the INTN /TEST pin for Software Development Mode entry, the device changes the mode without SPI command, the device will not enter/stay in Software Development Mode. CRC configuration detail The CRC is configured using the following scheme:

  • Pull-down on PWM1/CRC enable the CRC.
  • No external components on PWM1/CRC disables the CRC. In order to configure the CRC, the follow conditions have to be full filled:
  • Init Mode (from power-up) or Restart Mode
  • VCC1>Vrtx
  • POR=1
  • RSTN = LOW The configuration selection is done during the reset delay time t RD1 with a continuous filter time of tCFG_F and the configuration (depending on the voltage level at PWM1/CRC) is latched at the rising edge of RSTN. Figure 4 CRC configuration Selection Timi ng Diagram at the device power-up. In case of mismatch between CRC setting between the device and µC (CRC_STAT), the device can accept two recovery SPI commands (static patterns). The pattern 67AA AA0EH (addr + rw_bit = 67 ; data = AAAA ; CRC = 0E ) enables the CRC. The pattern E7AA AAC3H (addr + rw_bit = E7 ; data = AAAA ; CRC = C3) disables the CRC. The patterns shall be send only in Normal Mode. For additional details about the CRC setting and configuration, refer also to Chapter 11.3.1. t VCC1 t RSTN t VS_INT VPOR,r tRD1 VRT1,r tCFG_F Configuration selection monitoring period Continuous Filtering with

5.4 State Machine Modes Description

5.4.1 Init Mode

The device starts up in Init Mode after crossing the power-on reset VPOR,r threshold (see also Chapter 10.3) and the watchdog will start with a long open window (tLW) after RSTN is released (High level). In Init Mode, the device waits for the microcontroller to finish its startup and initialization sequence. Figure 6 Init Mode

5.4.2 Normal Mode

The Normal Mode is the standard operating mode for the device. The VCC1 is ac tive and all features are configurable. Supervision and monitoring features are enabled.

Datasheet 21 Rev. 1.0 2021-01-21

5.4.3 Stop Mode

The Stop Mode is the first level technique to reduce the overall current consumption VCC1 into a low-power mode. Note: All settings have to be done before entering Stop Mode. In Stop Mode any kind of SPI WRITE commands are ignored and the SPI_FAIL bit is set, except for changing to Normal Mode, triggering a device Soft Reset, refreshing the watchdog as well as for reading and clearing the SPI status registers. Note: A wake-up event on , WKx, Low-Side short circui t detection in parking braking mode or overvoltage brake detection, could generate an interrupt on pin INTN (based on INTN masking configuration; refer to Chapter 8) however, no change of the device mode will occur.

Datasheet 22 Rev. 1.0 2021-01-21 Note: In Stop Mode, it is possible to activate the Low-Si de of Bridge Drivers (e.g. in case of parking braking mode or overvoltage brake detection). Refer to Chapter 10.9 for additional details.

5.4.4 Sleep Mode

The Sleep Mode is the second level technique to re duce the overall current consumption to a minimum needed to react on wake-up events or for the device to perform autonomous actions . Note: All settings have to be done before entering Sleep Mode. Figure 9 Sleep Mode Note: In Sleep Mode, it is possible to activate the Low- Side’s of Bridge Drivers (e.g. in case of parking braking mode or overvoltage braking). Refer to Chapter 10.9 for additional details.

5.4.5 Restart Mode

The Restart Mode is a transition state where the RSNT pin is asserted.

Datasheet 23 Rev. 1.0 2021-01-21

5.4.6 Fail-Safe Mode

The purpose of this mode is to bring the system in a safe status after a failure condition by turning OFF VCC1 . After a wake event the system is then able to restart again. Figure 11 Fail-Safe Mode Note

  • In Fail-Safe Mode, the default wake sources WKx (if co nfigured as wake inputs) are activated automatically and all wake event bits will be cleared.
  • The Fail-Safe Mode will be maintained until a wake event on the default wake sources occurs. To avoid any fast toggling behavior a filter time of typ. 100ms (tFS,min) is implemented. Wake events during this time will be stored and will automatically lead to entering Restart Mode after the filter time. In case of an VCC1 overtemperature shutdown (TSD2) the Restart Mode will be reached automatically after a filter time of typ. 1s (tTSD2) without the need of a wake event once the device temperature has fallen below the TSD2 threshold.
  • The parking braking mode is automa tically disabled in Fail-Safe Mode. Table 9 Restart Mode Settings Part/Function Value Description VCC1 ON/ ramping

5.4.7 Software Development Mode

The Software Development Mode is a dedicated devi ce configuration especially useful for software development. Compared to the default device user mode operation, this mode is a super set of the state machine. The device will start also in Init Mode and it is possible to use all the modes and functions with following differences:

  • Restart Mode or Fail-Safe Mode (depending on the configuration) is not reached due to watchdog failure but the other reasons to enter these modes are still valid. Software Development Mode entry For timing and configuration details, refer to Chapter 5.2. Note
  • After Init Mode, the pull-up is released as the INTN/T EST pin acts as output then to drive the INTN signal.
  • If the device enters Fail-Safe Mode due to VCC1 shor t circuit to GND during the Init Mode, the Software Development Mode will not be entered and can only be reached at the next power-up of the device after the VCC1 short circuit is removed.
  • The absolute maximum ratings of the pin INTN must be observed. To increase the robustness of this pin during debugging or programming a series resistor between INTN and the connector can be added. Watchdog in Software Development Mode The Watchdog is enabled in Software Development Mode as default state. One INTN event is generated due to wrong watchdog trigger. It is possible to deactivate the integrated Watchdog module using the WD_SDM_DISABLE bit. After disabling the Watchdog, no INTN events are generated and the WD_FAIL bit will also not be set anymore in case of a trigger failure. It is also possible only to mask / un mask the INTN event of the WD in Software Development Mode by using the bit WD_SDM. In case of unmasking, a WD trigger fail will only lead to WD_FAIL bit set.

5.5 Transition Between States

This chapter describes the transiti on between the modes triggered by power-up, SPI commands or wake-up events.

5.5.1 Transition into Init Mode

The device goes into Init Mode in case of a power-up or after sending a soft-reset in Normal or Stop Mode. Prerequisites:

  • P o w e r O F F Table 11 Normal Mode Settings (Sof tware Development Mode active) Part/Function Default State

VCC1 ON •V C C 1 i s a c t i v e WD ON • WD is on, but will not trigger transi tion to Fail-Safe Mode or Restart Mode BD/CP OFF • The Bridge Drivers and Charge Pump may be configured and switched ON or OFF by SPI Cyc. Wake OFF •C a n b e c o n f i g u r e d

Datasheet 25 Rev. 1.0 2021-01-21

  • Device in Normal Mode or Stop Mode with follow conditions: –V S I N T > V P O R , r –R S T N H i g h Triggering Events:
  • A Soft Reset command ( MODE = ‘11’). All SPI registers will be changed to their respective Soft Reset values. Note
  • In case of Soft Reset command, a hardware RSTN ev ent can be generated depending on the configuration. An external Reset will be generated in case of SOFT_RESET_RO = 0 B . In case of SOFT_RESET_RO = 1B, no RSTN hardware event is generated in case of Soft Reset.
  • At power-up, the SPI bit VCC1_UV will not be set as long as VCC1 is below the VRT,x threshold and if VSINT is below the VSINT,UV threshold. The RSTN pin will be kept LOW as long as VCC1 is below the selected VRT1,r threshold. The reset delay counter will start after VRT1,r threshold is reached. After the first threshold crossing of VCC1 > VRT1,R and RSTN transition from low to high, all subsequent undervoltage events will lead to Restart Mode.
  • Wake events are ignored during Init Mode and will be lost.
  • T h e b i t VSINT_UV will only be updated in Init Mode once RSTN resumes a high level.

5.5.2 Init Mode -> Normal Mode

This transition moves the device in the mode where all configurations are accessable via SPI command. Prerequisites:

  • V S I N T > V P O R , r
  • I n i t M o d e
  • R S T N H i g h Triggering Events:
  • Any valid SPI command (from SPI protocol point of vi ew) will bring the device to Normal Mode (i.e. any register can be written, cleared and read) during the long open window where the watchdog has to be triggered (refer also Chapter 11.2). The CRC is not taken into account for this transition.
  • For example: – A SPI Sleep Mode command will still bring the device into Normal Mode. However, as this is an invalid state transition, the SPI bit SPI_FAIL is set. – Any invalid SPI command (from content point of view ) will still bring the device into Normal Mode. The SPI bit SPI_FAIL is set. Note
  • It is recommended to use the first SPI command to trigger and to configure the watchdog.

5.5.3 Normal Mode -> Stop Mode

This transition is intended as first measure to reduce the current consumption. All the device features needed in Stop Mode shall be configured in Normal Mode. Prerequisites:

  • VCC1>Vrtx
  • Device in Normal Mode Triggering Events:

Datasheet 26 Rev. 1.0 2021-01-21

  • State transition is only init iated by specific SPI command. Note
  • An interrupt is triggered on the pin INTN when Stop Mode is entered and not all wake source signalization flags were cleared.
  • If high-side switches are kept enabled during St op Mode, then the device current consumption will increase.
  • It is not possible to switch di rectly from Stop Mode to Sleep Mode. Doing so will also set the SPI_FAIL flag and will bring the device into Restart Mode.

5.5.4 Normal Mode -> Sleep Mode

This transition is intended to reduce as much as possible the current consumption keeping active only wake- up sources. All wake-up sources configurations shall be done in Normal Mode. Prerequisites:

  • VCC1>Vrtx
  • Device in Normal Mode
  • All wake source signalization flags were cleared (including the LSxDSOV_BRK bit)
  • At least one wake-u p source activated Triggering Events:
  • State transition is only init iated by specific SPI command. Note
  • I f VCC1_UV or VCC1_OV (with Config to go to Restart Mode) occurs at the border of the Sleep Mode entry: The device will go immeditaley into Restart Mode.
  • I f TSD2 or VCC1_OV (with Config to go to Fail-Safe Mode) occurs at the border of the Sleep Mode entry: The device will enter immediately Fail-Safe Mode.
  • As soon as the Sleep Mode command is sent, the Reset will go low.
  • It is not possible to switch all wake sources off in Sleep Mode. Doing so will set the SPI_FAIL flag and will bring the device into Restart Mode.

5.5.5 Stop Mode -> Normal Mode

This transition is intented to set the device in Norm al Mode where all the device integrated features are availbale and configurable. Prerequisites:

  • VCC1>Vrtx
  • Device in Stop Mode Triggering Events:
  • State transition is only initiated by SPI command. Note
  • N o n e

Datasheet 27 Rev. 1.0 2021-01-21

5.5.6 Sleep Mode -> Restart Mode

This transition is the consequence of a detection of wake-up event by the device. This transition is used to ramp up VCC1 after a wake in a defined way. Prerequisites:

  • Device in Sleep Mode
  • At least one wake-up source active Triggering Events:
  • A wake-up event on WKx, Cyclic Wake.
  • Bridge driver low-side short circuit detected duri ng overvoltage braking or in parking braking mode. Note
  • It is not possible to switch off all wake sources in Sleep Mode. Doing so will set the SPI_FAIL flag and will bring the device into Restart Mode.
  • RSTN is pulled low during Restart Mode.
  • The Restart Mode entry is signalled in the SPI register DEV_STAT.
  • The wake-up events are flaged in WK_STAT register or DSOV register.

5.5.7 Restart Mode -> Normal Mode

From Restart Mode, the device goes automatically to Normal Mode. Prerequisites:

  • Device in Sleep Mode or Fail-Safe Mode Triggering Events:
  • A u t o m a t i c
  • Reset is released Note
  • The watchdog timer will start with a long open window starting from the moment of the rising edge of RSTN and the watchdog period setting in the register WD_CTRL will be changed to the respective default value.

5.5.8 Fail-Safe Mode -> Restart Mode

This transition is similar to device from Sleep Mode to Restart Mode and consequence of a detection of wake- up event by the device. This transition is used to ramp up VCC1 after a wake in a defined way. Prerequisites:

  • Device in Fail-Safe Mode Triggering Events:
  • A wake-up event on WKx, TSD2 (rel eased over temperature TDS2 after t TSD2).
  • Bridge Driver Low Side short circui t detected during VS/VSINT overvoltage braking mode or in parking braking mode. Note: After leaving Fail-Safe Mode, the FAILURE bit in DEV_STAT register is set.

5.6 Reaction on Detected Faults

The device can react at some critical events either signalling the specific failure or changing the device mode. The chapter describes actions taken from the device in case of critical events in particular related the device mode change.

5.6.1 Stay in Current State

The following failures will not trigger any device mode changes, but will indicate the failures by an INTN event (depending from the Interrupt Masking) and in dedicated status registers:

  • Failures in Bridge Driver and/or Charge Pump

5.6.2 Transition into Restart Mode

The Restart Mode can be entered in case of failure as shown in following figure. Figure 12 Move into Restart Mode Prerequisites

  • In case of wake-up event from Sleep Mode or Fail Safe Mode
  • I n c a s e o f N o r m a l M o d e
  • In case of Stop Mode Trigger Events
  • VCC1 Undervoltage in case of Normal Mode or Stop Mode.

  • N o n e Restart Mode (RO pin is asserted) VCC1 ON/ ramping CP OFF WD OFF BD OFF Cyc. Wake OFF CSA OFF VCC1 over voltage (depend from VCC1_OV_MOD setting) VCC1 Under voltage Watchdog Failure Sleep Mode entry without any wake source enabled

Datasheet 29 Rev. 1.0 2021-01-21

5.6.3 Transition into Fail-Safe Mode

The Fail-Safe Mode can be entered in case of critical event as shown in the following figure. Figure 13 Move into Fail-Safe Mode Prerequisites:

  • Critical events on VCC1
  • Watchdog trigger failures Trigger Events:
  • Device thermal shutdown (TSD2) (see also Chapter 10.8.3).
  • VCC1 is shorted to GND (see also Chapter 10.7).
  • VCC1 over voltage (based on VCC1_OV_MOD).
  • 4 consecutive Watchdog trigger failure.
  • 4 consecutive VCC1 under voltage events.

5.7 Wake Features

Following wake sources are implemented in the device:

  • Static Sense: WKx inputs are perm anently active as wake sources.
  • Cyclic Wake: wake controlled by internal time rs, wake inputs are not used for cyclic wake.

5.7.1 Cyclic Wake

For the cyclic wake feature one timer is configured as internal wake-up source and will periodically trigger an interrupt on INTN in Normal Mode and Stop Mode. Du ring Sleep Mode, the timer triggers and wakes up the device again. The device enters via Restart Mode the Normal Mode. The correct sequence to configure the cyclic wake is shown in Figure 14. The sequence is as follows: VCC1 Short to GND TSD2 event Fail-Safe Mode VCC1 OFF CP OFF WD OFF BD OFF Cyc. Wake OFF CSA OFF After 4x consecutive Watchdog failure VCC1 over voltage (depend from VCC1_OV_MOD setting) After 4x consecutive VCC1 under voltage events (if VS_INT > VS_INT_UV)

Datasheet 30 Rev. 1.0 2021-01-21 Figure 14 Cyclic Wake: Configuration and Sequence Note: The on-time is only used to enable the cyclic wake function regardless of the value of the on time, i.e. the on time value has no meaning to the cyclic wake function as long as it is not ‘000’ or ‘110’ or ‘111’. The cyclic wake function will start as soon as the on-time is configured. An interrupt is generated for every start of the on-time except for the very first time when the timer is started.

5.7.2 Internal Timers

Two integrated timers can be used to control the below features:

  • Cyclic Wake, i.e. to wake up the microcontroller peri odically in Normal Mode, Stop Mode and Sleep Mode. Cyclic Wake Configuration Cyclic Wake starts / ends by setting / clearing On-time INTN is pulled low at every rising edge of On-time except first one Select Timer Period and any On-Time in TIMER_CTRL Periods: 10, 20, 50, 100, 200ms, 1s, 2s On-times: any (OFF/LOW & OFF/HIGH are not allowed) Disable Timer1 and Timer2 as a wake source in TIMER_CTRL To avoid unintentional interrupts Select Timer1 or Timer2 as a wake source in TIMER_CTRL No interrupt will be generated, if the timer is not enabled as a wake source

5.8 VS Supply Multiplexing

Figure 15 VS Supply Multiplexing The internal supply voltage is multiplexed from VSINT and VS, choosing continuously the larger of both. In case of transient low VBAT, the buffered supply voltage takes over the internal supply, avoiding loss of power. Note: Only the internal digital logic of the device is supplied by the VMAX SWITCH. In case of a power loss of either VS or VSINT, the internal register values will not be lost. MUX VSINT VS INTERNAL SUPPLY VMAX SWITCH

6 Voltage Regulator 1

VCC1 is a voltage reference for the current sense amplifier, for the SPI interface and for the PWM inputs. VCC1 has its own internal voltage regulator and may not be connected to the output of another voltage regulator.

6.1 Block Description

Figure 16 Module Block Diagram Functional Features

  • 5 V low-drop voltage regulator.
  • Undervoltage monitoring with adjustable reset le vel and VCC1 undervoltage prewarning (refer to Chapter 10.6 and Chapter 10.7 for more information).
  • Short circuit detection and switch off with undervoltage fail threshold, device enters Fail-Safe Mode.
  • Effective capacitance must be ≥1 µF at nominal voltage output for stability. A 2.2 µF ceramic capacitor (MLCC) is recommended for best transient response.
  • Output current capability up to IVCC1,lim. GND Overtemperature Shutdown Bandgap Reference VSINT State Machine VCC1 INH Vref

Datasheet 33 Rev. 1.0 2021-01-21

6.2 Functional Description

The Voltage Regulator 1 (=VCC1) is “ON” in Normal Mode and Stop Mode and is disabled in Sleep Mode and in Fail-Safe Mode. The regulator can provide an output current up to IVCC1,lim. For low-quiescent current reasons, the output voltage tolerance is decreased in Stop Mode because only the less accurate low-power mode regulator will be active for small loads. If the load current on VCC1 exceeds the selected threshold (I VCC1,Ipeak1,r or I VCC1,Ipeak2,r) then the high-power mode regu lator will be also activated to support an optimum dynamic load behavior. The curr ent consumption will then increase (approx. 2.8 mA additional quiescent current). The device mode stays unchanged. If the load current on VCC1 falls below the selected threshold (I VCC1,Ipeak1,f or IVCC1,Ipeak2,f), then the low-quiescent current mode is resumed again by disabling the high-power mode regulator. Both regulators (low-power mode and high-power mode) are active in Normal Mode. Two different active peak thresholds can be selected via SPI:

  • I_PEAK_TH = ‘0’(default): the lower VCC1 active peak threshold 1 is selected with lowest quiescent current consumption in Stop Mode.
  • I_PEAK_TH = ‘1’: the higher VCC1 active peak threshold 2 is selected with an increased quiescent current consumption in Stop Mode.

Datasheet 37 Rev. 1.0 2021-01-21

7.2 High-Voltage Wake Function

7.2.1 Functional Description

The wake inputs pin are edge-sensitive inputs with a switching threshold of typically 3 V. Both transitions, high to low and low to high, result in a signalization by the device. The signalization occurs either in triggering the interrupt in Normal Mode and Stop Mode or by a wake up of the device in Sleep Mode and Fail-Safe Mode. A filter time tFWKx is implemented to avoid an uninte ntional wake-up due to transients or EMC disturbances in static sense configuration. The filter time (tFWKx) is triggered by a level change crossing the switching threshold and a wake signal is recognized if the input level will not cross again the threshold during the selected filter time. Figure 18 shows a typical wake-up timing and filtering of transient pulses. Figure 18 Wake-up Filter Timing for Static Sense The wake-up capability for the WKx pin can be enabled or disabled via SPI command. A wake event via the WKx pin can always be read in the register WK_STAT. The actual voltage level of the WKx pin (low or high) can always be read in Normal Mode, Stop Mode and Init Mode in the register WK_LVL_STAT.

7.2.2 Wake Input Configuration

To ensure a defined and stable voltage levels at the in ternal comparator input it is possible to configure integrated current sources via the SPI register WK_CTRL. Table 13 Pull-Up / Pull-Down Resistor WKx_PUPD_ WKx_PUPD_ Current Sources Note 00n o c u r r e n t source WK input is floating if left open (default setting) 0 1 pull-down WK input internally pulled to GND VWKTh,f t VWKx tFWK No Wake Event Wake Event VWKth,f tFWK t VINTN tINTN

One additional configuration is related the filter time of each Wake-up module. The bits WK_FILT permit to set the filter time in static sensing. Note: When the device mode is changed to normal (from INIT ), in case of static sense, if the WK pin is set, the WK_STAT register is set in this time (also the interrupt pin). 1 0 pull-up WK input internally pulled to internal 5V supply 1 1 Automatic switching If a high level is detected at the WK input the pull-up source is activated, if low level is detected the pull down is activated.

8 Interrupt Function

8.1 Block and Functional Description

Figure 19 Interrupt Block Diagram The interrupt is used to signalize sp ecial events in real time to the mi crocontroller. The interrupt block is designed as a push/pull output stage as shown in Figure 19. An interrupt is triggered and the INTN pin is pulled low (active low) for t INTN in Normal Mode and Stop Mode and it is released again once t INTN is expired. The minimum high-time of INTN between two consecutive interrupts is tINTND. An interrupt does not cause a device mode change. Two different interrupt generation methods are implemented:

  • Interrupt Mask: One dedicated register (INT_MASK) is intended to enable or disable set of interrupt sources. The interrupt sources follow the SPI Status Information Field. In details: – SUPPLY_STAT: “OR” of all bits on SUP_STAT register except POR, VCC1_UV, VCC1_SC, VCC1_OV – TEMP_STAT: “OR” of all bits on THERM_STAT register except TSD2 – BD_STAT: “OR” of all bits on DSOV register – SPI_CRC_FAIL: or between SPI_FAIL and CRC_FAIL bits on DEV_STAT register.
  • Wake-up events: all wake-up events stored in the wake status SPI register WK_STAT only in case the corresponding input was configured as wake-up source. The wake-up sources are: –v i a W K p i n – via TIMERx (cyclic wake) – via LSx_DSOV_BRK if any of the brake-feature is enabled The methods are both available at the same time. Note: The errors which will cause Restart or Fail-S afe Mode (VCC1_UV, VCC1_SC, VCC1_OV, TSD2) are the exceptions of an INTN generation. Also the bit POR will not generate interrupts. If the above mentioned bits are not cleared after the device is back in Normal Mode or Stop Mode, the INTN is periodically generated (Register based cyclic interrupt generation). Note: Periodical interrupts are only generated by CRC fail and SPI fail from DEV_STAT register. INTERRUPT BLOCK.VSD Interrupt logic INTNTime out Vcc1

Datasheet 41 Rev. 1.0 2021-01-21 Note: During Restart Mode the SPI is blocked and the micr ocontroller is in reset. Therefore the INTN will not be in Restart Mode, which is the same behavior in Fail-Safe Mode or Sleep Mode. In addition to this behavior, INTN will be triggered when Stop Mode is entered and not all wake source bits were cleared in the WK_STAT register and also the LSx_DSOV_BRK bits in the DSOV register.. The SPI status registers are updated at every falling edge of the INTN pulse. All inte rrupt events are stored in the respective register until the register is cleared via SPI command. A second SPI read after reading out the respective status register is optional but recommended to verify that the interrupt event is not present anymore. The interrupt behavior is shown in Figure 20. The INTN pin is also used during Init Mode to select the Software Development Mode entry. See Chapter 5.2 for further information. In case of pending INTN event (SPI Status registers are not cleared after INTN event), additional periodical INTN events are generated as shown in Figure 21. The periodical INTN events generation can be disabled via SPI command using INTN_CYC_EN bit.

9 Gate Drivers

The TLE9185QX integrates six floating gate drivers capable of controlling a wide range of N-channel MOSFETs. They are configured as three high-sides and three low-sides, building three half-bridges. Figure 22 Half-bridge gate driver - Block diagram This section describes the MOSFET control in static activation and during PWM operation. Note: PWMx mentioned in this chapter refer to the PWMx pins and signal used by the bridge driver to control the external MOSFETs.

9.1 MOSFET control

Depending on the configuration bits HBxMODE[1:0] (refer to HBMODE), CPEN, each high-side and low-side MOSFETs can be:

  • Kept off with the passive discharge.

  • Activated (statically, no PWM, HBx_PWM_EN = 0).
  • Activated in PWM mode (HBx_PWM_EN = 1). Refer to Table 16 for details.

9.2 Static activation

In this section, we consider the st atic activation of the high-side and low-side MOSFET of the half-bridge x: HBx_PWM_EN= 0 (in ST_ICHG) and CPEN = 1.

The configured active cross-current protection and the Drain-Source overvoltage blank times for the Half- Bridge x are noted tHBxCCP ACTIVE and tHBxBLANK ACTIVE. The charge and discharge currents applied to the static controlled Half-Bridge x are noted ICHGSTx (ST_ICHG). IHARDOFF is the maximum current that the gate drivers can sink (150 mA typ.). This current is used to keep a MOSFET off, when the opposite MOSFET of the same half-bridge is being turned on. This feature reduces the risk of parasitic cross-current conduction. ICHGSTx is the current sourced, respec tively sunk, by the gate driver to turn-on the high-side x or low-side x. ICHGSTx is configured in the control register ST_ICHG.

Datasheet 46 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Gate Drivers IHOLD is the hold current used to keep the gate of the external MOSFETs in the desired state. This parameter is configurable with the IHOLD control bit in GENCTRL. If the control bit IHOLD = 0:

  • A MOSFET is kept ON with the current ICHG15.
  • A MOSFET is kept OFF with the current IDCHG15. If the control bit IHOLD = 1:
  • A MOSFET is kept ON with the current ICHG20.
  • A MOSFET is kept OFF with the current IDCHG20.

Turn-on with cross-current protection If LSx is ON (HBxMODE[1:0] = 01 B), before the activation of HSx (HBxMODE[1:0] = 10 B) then the high-side MOSFET is turned on after a cross-current protection time (refer to Figure 23):

9.2.2 Static activation of a low-side MOSFET

The description of the static activation of a low-side x differs from the description of Chapter 9.2.1 only by exchanging high-side x and low-side x.

9.2.3 Turn-off of the high-side and low-side MOSFETs of a half-bridge

9.3 PWM operation

The half-bridge can be controlled in PWM using either three or six PWM inputs. The TLE9185QX offers the possibility to detect the active and the freewhe eling (FW) MOSFET in each half- bridge.

9.3.1 Determination of the active and freewheeling MOSFET

If EN_GEN_CHECK = 1, right before each MOSFET acti vation, the device detects which MOSFET of the half- bridge is the active MOSFET and which MOSFET is the free-wheeling (FW) MOSFET:

  • If VSHx > VS - VSHH: The high-side MOSFET is the FW MOSFET and the low-side MOSFET is the active MOSFET.
  • If VSHx < VSHL: Then the low-side MOSFET is the FW MOSFET and the high-side MOSFET is the active MOSFET.
  • If VSHL < VSHx < VSHH: No clear distinction between the active FW MOSFET and the active MOSFET. The next MOSFET to be turned on is turned on as if it was the active MOSFET. If EN_GEN_CHECK = 0, the detection of the active and FW MOSFET is disabled. The PWM MOSFET is considered as the active MOSFET. Figure 26 shows the detection of the active and of the FW MOSFET.

Datasheet 51 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Gate Drivers Active gate control (AGC) The active gate control is configured by the control bi ts AGC[1:0]. The control scheme during the pre-charge and pre-discharge phases of:

  • T h e a c t i v e M O S F E T (EN_GEN_CHECK=1).
  • The PWM MOSFET ( EN_GEN_CHECK=0). can be selected. The following settings are possible:
  • Adaptive gate control (AGC[1:0] = (1,0) or (1,1), see GENCTRL): In this mode a pre-charge current and a pre- discharge current are applied to the gate of the controlled MOSFET. These currents are used to regulate effective the turn-on and turn-off delays to the respective target values.
  • No adaptive gate control (AGC[1;0] = (0,0)): in th is mode, the pre-charge and pre-discharge phases are deactivated.
  • No adaptive gate control (AGC[1;0] = (0,1)). In this mode: – During the pre-charge phase, the MOSFET is disc harged with the configured current IPCHGINIT (HB_PCHG_INIT). – During the pre-discharge phase, th e MOSFET is discharged with the configured current IPDCHGINIT (HB_PCHG_INIT). Note: It is recommended to configure tPCHGx < tHBxBL ANK Active and tPDCHGx < tHBxCCP Active (Refer to TPRECHG and CCP_BLK) independently from the AGC settings. Active free-wheeling (AFW) The active free-wheeling is activated for HBx if these conditions are fulfilled:
  • AFWx = 1 ( HBMODE)
  • HBx_PWM_EN = 1 ( HBMODE)
  • PWM_NB = 0 If AFWx = 1, a cross-current protection time is applied to HBx (set by CCP_BLK) during the PWM operation. If AFWx = 0, no cross current protection is applied to HBx during the PWM operation. The active free-wheeling reduces the power dissipation of the free-wheeling MOSFET. If an active MOSFET is OFF, the opposite MOSFET of the same half-bridge is actively turned on. Refer to Figure 30 and Figure 31.

  • one single precharge current is applied during tPDCHGx to regulate TDOFF If DEEP_ADAP = 1 (“deep adaptation” or “time modulation”) it is possible to:
  • to divide the precharge phase in two parts, during which two different precharge currents can be applied
  • to divide the predischarge phase in two parts, du ring which two different precharge currents can be applied Figure 38 describes the principle of the time modulation applied to the precharge phase. The same principle is also applied for the regulation of the pre-discharge phase.

9.3.3.4 Operation at high and low duty cycles

In the particular cases where the on -time is shorter than tHBxCCP FW or the off-time of the PWM signal is shorter than tHBxCCP Active:

  • No distinction between active MOSFET and FW MOSFET is possible. Therefore PWM MOSFET (selected by HBxMODE[1:0]) is controlled as active MOSFET.
  • The MOSFET opposite to the PW M MOSFET stays off (passive FW)

9.3.3.5 Measurements of the switching times

The effective switching times in PWM operation:

  • of the PWM MOSFET if EN_GEN_CHECK = 0
  • of the active MOSFET if EN_GEN_CHECK = 1 are reported in the registers: EFF_TDON_OFF1,EFF_TDON_OFF2,EFF_TDON_OFF3. If the end of the rise time for a gi ven MOSFET is not detected before tHBxBLANK Active elapses, then the corresponding status register reports an effective rise time equal to zero. If the end of the fall time for a gi ven MOSFET is not detected before tHBxCCP Active active elapses, then the corresponding status register reports an effective fall time equal to zero. The device cannot measure the switching times tDON, tDOFF, tRISE and tFALL at very high and very low duty cycles: tON < tHBxCCP FW and tOFF < tHBxCCP active. In this case, the corresponding registers report effective tDON, tDOFF, tRISE and tFALL equal to zero.

9.5 Slam mode

The slam mode is applicable in Normal Mode. If the SLAM bit is set in BRAKE register: 1. If HBxMODE = 01b or 10b , then the corresponding MOSFETs are actively turned off with their static discharge current during their respective tHBxCCP Active. 2. Then charge pump is deactivated independently from CPEN 3. Then PWM1/CRC input pin is ma pped to LS1, LS2, LS3, independently from PWM_NB, HBxMODE and HBx_PWM_EN a) If PWM1/CRC is High, then the low- side MOSFETs are turned on within tON_BRAKE. b) If PWM1/CRC is Low, then the low- side MOSFETs are turned off within tOFF_BRAKE. There is also the possibility to disable selectively the LSx in SLAM mode.

9.6 Parking braking mode

If PARK_BRK_EN bit is set, while the device goes in Sleep Mode or in Stop Mode: 1. If HBxMODE = 01b or 10b , then the corresponding MOSFETs are actively turned off with their static discharge current during their respective tHBxCCP Active. 2. Then charge pump is deactivated independently from CPEN bit. 3. Then the passive discharge ( RGGND) of the low-sides is deactivated, the passive discharge of the high-sides are activated 4. If PWM1/CRC is High, then the low- side MOSFETs are turned on within tON_BRAKE. Refer to Chapter 10.9.2 for the protection of the of low-side MOSFETs against short circuits when the parking braking mode is activated.

The buffer capacitor between VS and CP must have a capacitance equal or higher than 470 nF. Figure 44 Charge pump - Block diagram Logic or normal level MOSFETs The regulation of the charge pump outputs voltage can be configured depending on the type of MOSFET. FET_LVL = 0: Logic level MOSFETs are selected:

  • V C P - V S = VCP3 (11 V typ. at VS > 8 V).
  • The high-side gate-source voltage GHx - SHx is VGH4 (VS > 8 V).
  • The low-side gate-source voltage GLx - SL is VGH3 (VS > 8 V). FET_LVL = 1: Normal level MOSFETs are selected:
  • V C P - V S = VCP1(15 V typ. at VS > 8 V).
  • The high-side and low-side gate-source voltage GHx - SHx or GLx - SL is VGH1 (VS > 8 V). CPSTGA = 0 (default, see GENCTRL), the device operates with the dual-stage charge pump. If CPSTGA = 1, the device switches to single-stage or dual-stage charge pump automatically:
  • I f VS > VCPSO DS: the TLE9185QX switches from a dual-stage to a single-stage charge pump.
  • I f VS < VCPSO SD: the TLE9185QX switches from single-stage to dual-stage charge pump. The operation with the single-stage charge pump reduces the current consumption from the VS pin. Single/dual stage charge pump Pr ec har ge VS CPC1N CPC1P CPC2N CPC2PCP CCP ≥ 470 nF CCP1 CCP2 Logic

9.8 Frequency modulation

A modulation of the charge pump frequency can be activated to reduce the peak emission. The modulation frequency is set by the control bit FMODE in GENCTRL:

  • FMODE = 0: No modulation.
  • FMODE = 1: Modulation fr equency = 15.6 kHz (default).

10 Supervision Functions

10.1 Reset Function

Figure 45 Reset Block Diagram

10.1.1 Reset Output Description

The reset output pin RSTN provides a reset information to the microcontroller, for example, in the event that the output voltage has fallen below the undervoltage threshold VRTx. In case of a reset event, the reset output RSTN is pulled to low after the filter time tRF and stays low as long as the reset event is present plus a reset delay time tRD1 or tRD2 depending on the value in RSTN_DEL. When connecting the device to battery voltage, the reset signal remains low initially. When the output voltage VCC1 has reached the reset default threshold VRT1,r, the reset output RSTN is released to high after the reset delay time tRD1. A reset can also occur due to a watchdog trigger failure. The reset threshold can be adjusted via SPI, the default reset threshold is VRT1,f. The RSTN pin has an integrated pull-up resistor. In ca se reset is triggered, it will be pulled low for VCC1 ≥ 1V and for VSINT ≥ VPOR,f (see also Chapter 10.3). The timings for the RSTN triggering regarding VCC1 undervoltage and watchdog trigger is shown in Figure 46. Reset logic Incl. filter & delay RSTN VCC1

10.1.2 Soft Reset Description

In Normal Mode and Stop Mode, it is also possible to trigger a device internal reset via a SPI command in order to bring the device into a de fined state in case of failures. In this case the microcontroller must send a SPI command and set the MODE bits to ‘11’ in the M_S_CTRL register. As soon as th is command becomes valid, the device is set back to Init Mode and all SPI registers are set to their default values (see SPI Chapter 11.5.1 and Chapter 11.6.1). Two different soft reset configurations are possible via the SPI bit SOFT_RESET_RO:

  • SOFT_RESET_RO = ‘0’: The reset output (RSTN) is triggered when the soft reset is executed (default setting) The configured reset delay time tRD1 or tRD2 is applied depending on the value in RSTN_DEL).
  • SOFT_RESET_RO = ‘1’: The reset output (RSTN) is not triggered when the soft reset is executed. Note: The device must be in Normal Mode or Stop Mode when sending this command. Otherwise, the command will be ignored. Note: Allow CRC configuration after software-reset - or better check once again via SPI after software reset. The reset threshold can be configured via SPI in Normal Mode, default is VRT1 tRD1 tLW Init RSTN SPI t VCC1 VRT1 undervoltage tRDx (config) Normal t t tLW t < tRF tRF tCW Restart Normal SPI Init Reset_timing.vsd tCW tOW WD Trigger tCW tOW WD Trigger SPI Init tLW= long open window tCW= closed window tOW= open window

10.2 Watchdog Function

The watchdog is used to monitor the communication with the microcontroller and to trigger a reset or move the device to Fail Safe Mode, if the microcontroller stops serving the watchdog. Two different types of watchdog functions are implemented and can be selected via the bit WD_CFG:

  • Time-Out Watchdog (default value)
  • W i n d o w W a t c h d o g The respective watchdog functions can be selected and programmed in Normal Mode. The configuration stays unchanged in Stop Mode. Please refer to Table 27 to match the device modes with the respective watchdog modes. The watchdog timing is programmed via SPI command in the register WD_CTRL. As soon as the watchdog is programmed, the timer starts with the new setting and the watchdog must be served. The watchdog is triggered by sending a valid SPI-write command to the watchdog configuration register. The watchdog trigger command is executed when the SPI command is interpreted. When coming from Init Mode, Restart Mode or in certain cases from Stop Mode, the watchdog timer is always started with a long open window. The long open window ( t LW) allows the microcontroller to run its initialization sequences and then to trigger the watchdog via SPI. The watchdog timer period can be selected via SPI ( WD_TIMER).The timer setting is valid for both watchdog types. The following watchdog timer periods are available:
  • WD Setting 1: 10 ms
  • WD Setting 2: 20 ms
  • WD Setting 3: 50 ms
  • WD Setting 4: 100 ms
  • WD Setting 5: 200 ms
  • WD Setting 6: 500 ms
  • WD Setting 7: 1 s
  • WD Setting 8: 10 s In case of a reset, Restart Mode or Fail-Safe Mode is entered according to the co nfiguration and the SPI bits WD_FAIL are set. Once the RSTN goes high again the watc hdog immediately starts with a long open window the device enters automatically Normal Mode. The Watchdog behaviour in Software Development Mode is described in Chapter 5.4.7. Table 27 Watchdog Functionality by modes Mode Watchdog Mode Remarks Init Mode Starts with Long Open Window Watchdog starts with Long Open Window after RSTN is released. Normal Mode WD Programmable Window Watchdog, Time-Out watchdog or switched off for Stop Mode. Stop Mode Watchdog is fixed or off Sleep Mode Off Device will start with Long Open Window when entering Normal Mode. Restart Mode Off Device will start with Long Open Window when entering Normal Mode.

Datasheet 94 Rev. 1.0 2021-01-21 In case a watchdog-trigger was missed in Software Development Mode, the watchdog will start with the long- open-window once again. The WD_FAIL bits will be set after a watchdog trigger failure. The WD_FAIL bits are cleared automatically when following conditions apply:

  • After a successful watchdog trigger.
  • When the watchdog is off: in Stop Mo de after successfully disabling it, in Sleep Mode, or in Fail-Safe Mode (except for a watchdog failure).

10.2.1 Time-Out Watchdog

The time-out watchdog is an easier and less secure watchdog than a window watchdog as the watchdog trigger can be done at any time within the configured watchdog timer period. A correct watchdog service immediately results in starting a new watchdog timer period. Taking the tolerances of the internal oscillator into account leads to the safe trigger area as defined in Figure 47. If the time-out watchdog period elapses, a watchdog reset is created by setting the reset output RSTN low and the device switches to Restart Mode or Fail-Safe Mode. Figure 47 Time-out Wa tchdog Definitions open window t / [tWD_TIMER ] safe trigger area Watchdog Timer Period (WD_TIMER) uncertainty Typical timout watchdog trigger period tWD x 1.80tWD x 1.20 tWD x 1.50

Datasheet 95 Rev. 1.0 2021-01-21

10.2.2 Window Watchdog

Compared to the time-out watchdog the characteristic of the window wa tchdog is that the watchdog timer period is divided between a closed and an open wind ow. The watchdog must be triggered within the open window. A correct watchdog trigger results in starting the window watchdog period by a closed window followed by an open window. The watchdog timer period is at the same time the ty pical trigger time and defi nes the middle of the open window. Taking the oscillator tolerances into account leads to a safe trigger area of: tWD × 0.72 < safe trigger area < tWD × 1.20. The typical closed window is defined to a width of 60% of the selected window watchdog timer period. Taking the tolerances of the internal oscillator into account leads to the timings as defined in Figure 48. A correct watchdog service immediately results in starting the next closed window. If the trigger signal meet the closed window or if the watchdog timer period elapses, then a watchdog reset is triggered (RSTN low) and the device switches to Restart Mode or Fail-Safe Mode. Figure 48 Window Watchdog Definitions

10.2.3 Watchdog Setting Check Sum

A check sum bit is part of the SPI command to trigger the watchdog and to set the watchdog setting. The sum of the 16 data bits in the register WD_CTRL needs to have even parity (see Equation (10.1)). This is realized by either setting the bit CHECKSUM to 0 or 1. If the check sum is wrong, then the SPI command is ignored, i.e. the watchdog is not triggered or the settings are not changed and the bit SPI_FAIL is set. The written value of the reserved bits of the WD_CTRL register is considered (eve n if read as ‘0’ in the SPI output) for checksum calculation, i.e. if a 1 is written on the reserved bit position, then a 1 will be used in the checksum calculation.

10.2.4 Watchdog during Stop Mode

The watchdog can be disabled for Stop Mode in Normal Mode. For safety reasons, there is a special sequence to be followed in order to disa ble the watchdog as described in Figure 49. Two different SPI bits (WD_STM_EN_0, WD_STM_EN_1) in the registers HW_CTRL and WD_CTRL need to be set. Figure 49 Watchdog disablin g sequence in Stop Mode If a sequence error occurs, then the bit WD_STM_EN_1 will be cleared and the sequence has to be started again. The watchdog can be enabled by triggering the watchdog in Stop Mode or by switching back to Normal Mode via SPI command. In both cases the watchdog will start with a long open window and the bits WD_STM_EN_1 and WD_STM_EN_0 are cleared. After the long open window the watchdog has to be served as configured in the WD_CTRL register. Note: The bit WD_STM_EN_0 will be cleared automatically when the sequence is started and it was 1 before. WD_STM_EN_0 can also not be set if WD_STM_EN_1 isn't yet set.

10.3 VSINT Power On Reset

At power up of the device, the Power on Reset is detected when VSINT > VPOR,r and the SPI bit POR is set to indicate that all SPI registers are set to POR default setti ngs. VCC1 is starting up and the reset output will be kept low and will only be released once VCC1 has crossed VRT1,r and after tRD1 has elapsed. In case VSINT < VPOR,f, an device internal reset will be generated and the device is switched off and will restart in Init Mode at the next VSINT rising. This is shown in Figure 50. Figure 50 Ramp up / down example of Supply Voltage t VCC1 t VPOR,f RSTN t VSINT VPOR,r tRD1 VRT1,r VRTx,f t Mode OFF OFFINIT MODE Any MODE SPI Command The reset threshold can be configured via SPI in Normal Mode, default is VRT1 Re- start Restart Mode is entered whenever the Reset is triggered

10.4 VSINT Under- and Overvoltage

10.4.1 VSINT Undervoltage

The VSINT under-voltage monitoring is always active in Init Mode, Restart Mode, Normal Mode. If the supply voltage VSINT drops below VSINT,UV for more than tVSUV_FILT, then the device does the following measures:

  • The VCC1 short circuit diagnosis becomes inactive (see Chapter 10.7). However, the thermal protection of the device remains active. If the undervoltage threshold is exceeded (VSINT rising) then the function will be automatically enabled again.
  • The status bit VSINT_UV is set and latched until a clear command of SUP_STAT is received. Note: VSINT under-voltage monitoring is not availabl e in Stop Mode due to current consumption saving requirements except if the VCC1 load current is above the active peak threshold (I_PEAK_TH) or if VCC1 is below the VCC1 prewarning threshold.

10.4.2 VSINT Overvoltage

The VSINT over-voltage monitoring is always active in Init Mode, Restart Mode and Normal Mode. If VSINT rises above VS,OVD1, VS,OVD2 for more than tVSOV_FILT then the device does the following measures: 1. If HBxMODE = 01b or 10b , then the corresponding MOSFETs are actively turned off with their static discharge current during their respective tHBxCCP Active. 2. Then the charge pump is turned off and the passive discharge is activated. 3. The status bits VSINT_OV is set and latched until a clear command of SUP_STAT is received. If VS or VSINT fall below VS,OVD1 or VS,OVD2:

  • I f CPEN = 0 : the charge pumps stays and the bridge driver stay off.
  • I f CPEN = 1 : –I f BDOV_REC = 0 : Then the charge pump is reactivated but the bridge driver stays off until VS_OV and VSINT_OV are cleared. The current sense amplifier is reactivated (provided that CSA_OFF = 0) –I f BDOV_REC = 1 : Then the charge pump and the current sense amplifier are reactivated and the bridge driver is enabled if VCP > VCPUVx, even if VS_OV or VSINT_OV is set. The state of the external MOSFETs is according to the control registers.

Datasheet 99 Rev. 1.0 2021-01-21

10.5 VS Under- and Overvoltage

10.5.1 VS Undervoltage

The VS under-voltage monitoring is always active in In it-, Restart Mode and Normal Mode. If VS drops below VS,UV for more than tVSUV_FILT, then the device does the following measures: 1. If HBxMODE = 01b or 10b , then the corresponding MOSFETs are actively turned off with their static discharge current during their respective tHBxCCP Active. 2. Then the charge pump is turned of f and the passive discharge is activated and the current sense amplifier is turned off. 3. The status bits VS_UV is set and latched until a clear command of SUP_STAT is received. If VS rises above VS,UV, then the charge pump is reactivated (provided that CPEN is set) and the current sense amplifier is reactivated (provided CSA_OFF = 0) but the bridge driver stays off until VS_UV is cleared. The bridge driver will be reactivated once the VS_UV bit is cleared.

10.5.2 VS Overvoltage

The VS over-voltage monitoring is always active in Init-, Restart Mode and Normal Mode or when the charge pump is enabled. If VS rises above VS,OVD1 or VS,OVD2 for more than tVSOV_FILT, then the device does the following measures: 1. If HBxMODE = 01b or 10b , then the corresponding MOSFETs are actively turned off with their static discharge current during their respective tHBxCCP Active. 2. Then the charge pump is turned off and the passive discharge is activated and current sense amplifier is turned off . 3. The status bits VS_OV is set and latched until a clear command of SUP_STAT is received. If VS and VSINT fall below VS,OVD1 or VS,OVD2:

  • I f CPEN = 0 : the charge pumps and the bridge driver stay off.
  • I f CPEN = 1 : –I f BDOV_REC = 0 : Then the charge pump is reactivated (provided that CPEN = 1 and CP_UV = 0) but the bridge driver stays off until VS_OV and VSINT_OV are cleared. The current sense amplifier is reactivated provided that CSA_OFF = 0 –I f BDOV_REC = 1 : Then the charge pump and the current sense amplifier are reactivated and the bridge driver is enabled if VCP > VCPUVx, even if VS_OV or VSINT_OV is set. The state of the external MOSFETs is according to the control registers.

10.6 VCC1 Over-/ Undervoltage and Undervoltage Prewarning

10.6.1 VCC1 Undervoltage and Undervoltage Prewarning

This function is always active when the VCC1 voltage regulator is enabled. A first-level voltage detection threshold is implemented as a prewarning for the microcontroller. The prewarning event is signaled with the bit VCC1_WARN. No other actions are taken. As described in Chapter 10.1 and Figure 51, a reset will be triggered (RSTN pulled low) when the VCC1 output voltage falls below the selected undervoltage threshold (VRTx). The device will enter Restart Mode and the bit VCC1_UV is set when RSTN is released again. The hysteresis of the VCC1 undervoltage threshold can be increased by setting the bit RSTN_HYS. In this case always the highest rising threshold ( VRT1,R) is used for the release of the un dervoltage reset. The falling reset threshold remains as configured. An additional safety mechanism is implemented to av oid repetitive VCC1 undervoltage resets due to high dynamic loads on VCC1:

  • A counter is increased for every consecutive VCC1 un dervoltage event (regardless on the selected reset threshold).
  • The counter is active in Init Mode, Normal Mode and Stop Mode.
  • F o r V S < VSINT,UV the counter will be stopped in Normal Mode (i.e. the VS UV comparator is always enabled in Normal Mode).
  • A 4th consecutive VCC1 undervoltage event will lead to Fail-Safe Mode entry and to setting the bit VCC1_UV_FS.
  • This counter is cleared: – When Fail-Safe Mode is entered. – When the bit VCC1_UV is cleared. – When a Soft-Reset is triggered. Note: After 4 consecutive VCC1_UV events, th e device will enter Fail-Safe Mode and the VCC1_UV_FS bit is set. Note: The VCC1_WARN or VCC1_UV bits are not set in Sleep Mode as V CC1 = 0 V in this case. Figure 51 VCC1 Undervol tage Timing Diagram RSTN t VCC1 VRTx tRDx (config) Normal Mode t tRF Restart Mode Normal Mode

Datasheet 101 Rev. 1.0 2021-01-21 Note: It is recommended to clear the VCC1_WARN and VCC1_UV bit once it is detected by the microcontroller software to verify if the undervoltage still exists or not.

10.6.2 VCC1 Overvoltage

For fail-safe reasons a configurable VCC1 over voltage detection feature is implemented. It is active when the VCC1 voltage regulator is enabled. In case the VCC1,OV,r threshold is crossed, the device trigge rs following measures depending on the configuration:

  • T h e b i t VCC1_OV is always set.
  • Based on the configuration of VCC1_OV_MOD, different kind of event are generated from device.
  • I f t h e VCC1_OV_MOD=11B, in case of the device enters in Fail Safe Mode. Figure 52 VCC1 Over Voltage Timing Diagram

10.7 VCC1 Short Circuit Diagnostics

The short circuit protection feature for VCC1 is implemented as follows:

  • The short circuit detection is only enabled if VS > VSINT,UV.
  • If VCC1 is not above the V RTx within tVCC1,SC after device power up or after waking from Sleep Mode or Fail- Safe Mode (i.e. after VCC1 is enabled) then the SPI bit VCC1_SC bit is set, VCC1 is turned off, the FO pin is enabled, FAILURE is set and Fail-Safe Mode is entered. The device can be activated again via a wake-up sources.
  • The same behavior applies, if VCC1 falls below VRTx for longer than tVCC1,SC. RSTN t VCC1 tRDx (config) Normal Mode t tOV_filt Restart Mode Normal Mode VCC1,OV

Datasheet 102 Rev. 1.0 2021-01-21

10.8 Thermal Protection

Three independent and different thermal protection features are implemented in the device according to the system impact:

  • Individual thermal shutdo wn of specific blocks
  • Temperature prewarning of VCC1 voltage regulator
  • Device thermal shutdown due to VCC1 overtemperature

10.8.1 Individual Thermal Shutdown

As a first-level protection measure, the charge pump is independently sw itched off if the respective block reaches the temperature threshold TjTSD1. Then the TSD1 bit is set. This bit can only be cleared via SPI once the overtemperature is not present anymore. Inde pendent of the device mo de the thermal shutdown protection is only active if the respective block is ON. The respective modules behave as follows:

  • Charge pump: If the charge pump reaches T jTSD1, then CP_OT is set, CPEN is cleared and the activated MOSFETs are actively discharged with their respective static currents during their respective active cross current protection times (tHBxCCP active). When all tHBxCCP active elapsed, then the charge pump and the MOSFETs active discharge are disabled and the current sense amplifier is deactivated. Once the over temperature condition is not present anymore, then CPEN has to be configured again by SPI. Note: The diagnosis bits are not cleared automatically and have to be cleared via SPI once the overtemperature condition is not present anymore.

10.8.2 Temperature Prewarning

As a next level of thermal protection a temperature prewarning is implemented if the main supply VCC1 reaches the thermal prewarning temperature threshold TjPW. Then the status bit TPW is set. This bit can only be cleared via SPI once the overtemperature is not present anymore.

10.8.3 Thermal Shutdown

As a highest level of thermal protec tion a temperature shutdown of the device is implemented if the main supply VCC1 reaches the thermal shutdown temperature threshold TjTSD2. Once a TSD2 event is detected Fail- Safe Mode is entered. Only when device temperature falls below the TSD2 threshold then the device remains in Fail-Safe Mode for tTSD2 to allow the device to c ool down. After this time has expired, the device will automatically change via Restart Mode to Normal Mode (see also Chapter 5.4.6). When a TSD2 event is detected, then the status bit TSD2 is set. This bit can only be cleared via SPI in Normal Mode once the overtemperature is not present anymore. For increased robustness requirements it is possible to extend th e TSD2 waiting time by 64x of tTSD2 after 16 consecutive TSD2 events by setting the SPI bit TSD2_DEL. The counter is incremented with each TSD2 event even if the bit TSD2 is not cleared. Once the counter has reached the value 16, then the bit TSD2_SAFE is set and the extended TSD2 waiting ti me is active. The extended waiting time will be kept until TSD2_SAFE is cleared. The TSD counter is cleared when TSD2 or TSD2_DEL is cleared. Note: In case a TSD2 overtemperature occurs while en tering Sleep Mode then Fail-Safe Mode is still entered. Note: In case of a TSD2 event, the FAILURE bit is set to ‘1’ and the DEV_STAT field is set to ‘01’ inside the DEV_STAT register.

10.9 Bridge driver

This section describes the supervision functions related to the bridge driver.

10.9.1 Bridge driver supervision with activated charge pump

This section describes the supervision functions when the charge pump is activated.

10.9.1.1 Drain-source voltage monitoring

Voltage comparators monitor the activated MOSFETs to protect high-side MOSFETs and low-side MOSFETs against a short circuit respectively to ground and to the battery during ON-state. A drain-source overvoltage is detect ed on a low-side MOSFET if the voltage difference between VSHx and SL exceeds the threshold vo ltage configured by LS_VDS (see Table 28). Consequently, the corresponding half- bridge is latched off with the static discharge current. A drain-source overvoltage is detected on a high-side MOSFET if the voltage difference between VS and VSHx exceeds the threshold vo ltage configured by HS_VDS (see Table 29). Consequently, the corresponding half- bridge is latched off with the static discharge current. Attention: 2 V threshold is dedicated for the diagnostic in off-state. It is highly recommended to select another drain-source overvoltage threshold once the routine of the diagnostic in off-state has been performed to avoid additional current consumption from VS and from the charge pump. The device reports a Drain-Source overvoltage error if both conditions are met: Table 28 Low-side drain-source overvoltage threshold LSxVDSTH[2:0] Drain-Source overvolt age threshold for LSx (typical) 000B 160 mV 001B 200 mV (default) 010B 300 mV 011B 400 mV 100B 500 mV 101B 600 mV 110B 800 mV 111B 2 V Table 29 High-side drain-sour ce overvoltage threshold HSxVDSTH[2:0] Drain-Sou rce overvoltage threshold for HSx (typical) 000B 160 mV 001B 200 mV (default) 010B 300 mV 011B 400 mV 100B 500 mV 101B 600 mV 110B 800 mV 111B 2 V

Datasheet 104 Rev. 1.0 2021-01-21

  • After expiration of the blank time .
  • If the Drain-Source voltage monitoring exceeds the co nfigured threshold for a duration longer than the configured filter time (refer to Table 30 and LS_VDS TFVDS bits). If a short circuit is detected by the Drain-Source voltage monitoring:
  • The impacted half-bridge is latched off with the stat ic discharge current for the configured cross-current protection time.
  • The corresponding bit in the status register DSOV is set.
  • The DSOV bit in Global Status Register GEN_STAT is set. If a Drain-Source overvoltage is detected for one of the MOSFETs, then the status register DSOV must be cleared in order to re-enable the faulty half-bridge.

10.9.1.2 Cross-current protection and drain-source overvoltage blank time

All gate drivers feature a cross-current protection time and a Drain-Source overvoltage blank time. The cross-current protection avoids the simultaneous activation of the high-side and the low-side MOSFETs of the same half-bridge. During the blank time, the drain-source overvoltage de tection is disabled, to avoid a wrong fault detection during the activation phase of a MOSFET. Note: The setting of the cross-current protection and of the blank times may be changed by the microcontroller only if all HBx_PWM_EN bits are reset. Note: Changing the Drain-Source overvoltage of a half -bridge x (HBx) in on-state (HBxMODE[1:0]=(0,1) or (1,0)) may result in a wrong VDS overvoltage detection on HBx. Therefore it is highly recommended to change this threshold when HBxMODE[1:0]=(0,0) or (1,1)

10.9.1.2.1 Cross-current protection

The active and freewheeling cross-current protection times of each half-bridge is configured individually with the control register CCP_BLK. The typical cross-current protection time applied to th e freewheeling MOSFET of the half-bridge x is 587 ns + 266 ns x TCCP[3:0]D, where TCCP[3:0]D is the decimal value of the control bits TCCP.

10.9.1.2.2 Drain-source overvoltage blank time

A configurable blank time for the Drain-Source monitori ng is applied at the turn -on of the MOSFETs. During the blank time, a Drain-Source overvoltage error is masked. Table 30 Drain-Source overvoltage filter time TFVDS[2:0] Drain-Source overvoltage filter time (typical) 00B 0.5 µs (default) 01B 1 µs 10B 2 µs 11B 6 µs

Datasheet 105 Rev. 1.0 2021-01-21 For Half-Bridges in PWM mode with AFWx = 1:

  • the blank time of the PWM MOSFET starts at the expira tion of the cross-current protection time of the PWM MOSFET. Refer to Figure 53.
  • the blank time of the free-wheeling MOSFET starts after expiration of the cross-current protection time at turn-off of the PWM MOSFET. Refer to Figure 53. Figure 53 Blank time for half-bridg es in PWM operation with AFW = 1 For statically activated half-bridges, the blank time starts:
  • Case1: at expiration of the cross-current protection ( Figure 23), if the opposite MOSFET was previously activated.
  • Case 2: right after the decoding of the SPI command to turn on a MOSFET, if the half-bridge was in high impedance (Figure 24). The blank times of the active and FW MOSFETs can be configured with the control register CCP_BLK. The typical blank is 587 ns + 266 ns x TBLK[3:0]D). Note: The blank time is implemented at every new acti vation of a MOSFET, including a recovery from VS undervoltage, VS overvoltage, VSINT overvoltage, CP UV, CP OT.

10.9.1.3 OFF-state diagnostic

In order to support the off-st ate diagnostic (HBxMODE= 11 and CPEN = 1), the gate driver of each MOSFET provides pull-up (IPUDiag) and a pull-down currents (IPDDiag) at the SHx pins. This function requires an activated charge pump. The pull-up current source of a given half-bridge is on when the half-bridge is active: HBxMODE= 01, 10 or 11 and CPEN = 1. The pull-down current of each low-side gate dr iver is activated by the control bits HBx ( HB_ICHG_MAX register). During the off-state diagnostic routine performed by the microcontroller, the drain-source overvoltage threshold of the relevant half-bridges m u s t b e s e t t o 2 V n o m i n a l . R e f e r t o Table 28. Once the routine is finished, it is highly recommended to decrease the drain-source overvoltage th reshold to a lower value, avoiding additional current consumption from the VS input.

Datasheet 106 Rev. 1.0 2021-01-21 The following failures can be detected:

  • MOSFET short circuit to GND
  • MOSFET short circuit the battery
  • Open load (disconnected motor) The status of the output voltages VOUTx, can be read back with status bit HBxVOUT (register GEN_STAT) when the corresponding half-bridge is in off-state (HBxMODE[1:0] = 11). Note: HBxVOUT = 0 if the half-bridge x is not active ly off (HBxMODE[1:0] = (0,0), (0,1) or (1,0) and CPEN=1) or when the charge pump is deactivated (CPEN=0).

10.9.1.4 Charge pump undervoltage

The voltage of the charge pump output (VCP) is monitored in order to ensure a correct control of the external MOSFETs. The charge pump undervoltage threshold is configurable by the control bits FET_LVL and CPUVTH. If VCP falls below the configured charge pump undervoltage threshold while CPEN = 1:

  • If one of the MOSFET is on, then al l MOSFETs are actively turned off with their configured static discharge current during their respective tHBxCCP active.
  • Then the gate drivers are turned off and CSA is turned off .
  • CP_UV is set and latched. The CP_UV is reset and the normal operation is resumed once SUP_STAT is cleared and VCP > VCPUV. The charge pump undervoltage detection is blanked ( tCPUVBLANK) during each new activation of the charge pump1).

10.9.1.5 Switching parameters of MOSFETs in PWM mode

The effective switching paramete rs of the active MOSFETs ( EN_GEN_CHECK=1), respectively PWM MOSFET (EN_GEN_CHECK=0)can be read out with dedicated status registers:

  • The turn-on and turn off delays, noted tDON an d tDOFF are reported by the status register EFF_TDON_OFF1, EFF_TDON_OFF2, EFF_TDON_OFF3.
  • The rise and fall times, noted tRISE and tF ALL, are reported by the status register TRISE_FALL1, TRISE_FALL2, TRISE_FALL3.

10.9.2 Low-side drain-source volt age monitoring during braking

The low-side MOSFETs are turned-on while the charge pump is deactivated in the following conditions:

  • The slam mode is activated and PWM1/CRC is High. Table 31 Charge pump un dervoltage thresholds FET_LVL = 0 FET_LVL = 1 CPUVTH = 0 VCPUV1 (6 V typ. referred to VS) VCPUV3 (7.5 V typ. referred to VS) CPUVTH = 1 VCPUV2 (6.5 V typ. referred to VS) VCPUV4 (8 V typ. referred to VS) 1) Including CPEN set to 1, recovery from VS under/overvoltage, VSINT overvoltage and CP_ OT

  • The parking braking mode is activated and th e device is in Sleep Mode or Stop Mode.
  • VS overvoltage brake is activated an d (VS > VS Overvoltage braking or VSINT > VSINT Overvoltage braking) in all device modes if OV_BRK_EN is set. Under these conditions, the drain-source voltage of the low-sides are monitored and the applied drain-source overvoltage thresholds are according to VDSTH_BRK. The applied blank time, which starts at the beginning of the brake activation, is:
  • tBLK_BRAKE1 if TBLK_BRK = 0
  • tBLK_BRAKE2 if TBLK_BRK = 1 During the blank time, a drain-source overvoltage of the low-sides is masked. The applied filter time is tFVDS_BRAKE. If a drain-source overvoltage is dete cted during braking , then all low-si de MOSFETs are turned off (latched) within tOFF_BRAKE. SLAM_LSx_DIS ( BRAKE, SLAM, PARK_BRK_EN, OV_BRK_EN are unchanged. The corresponding status bit LSxDSOV_BRK is set in DSOV. The low-sides can be reactivated only if all LSxDSOV_BRK bits (DSOV) are cleared (even in slam mode with the respective LSx disabled by the SLAM_LSx_DIS bit). If any of the status bits LSxDSOV_BRK is set, then th e charge pump stays off ( CPEN=1 command is accepted but the charge pump stays disabled until all LSxDSOV_BRK are cleared).

10.9.3 VS or VSINT Overvoltage braking

The VS and VSINT overvoltage braking is activated if the OV_BRK_EN bit in BRAKE register is set regardless of the device mode. If VS, respectively VSINT, exceeds VOVBR,cfgx,r (x = 0 to 7), then all low-sides MOSFETs are turned-on within tON_BRAKE. The status bits VSOVBRAKE_ST, respectively VSINTOVBRAKE_ST, is set and latched (see DSOV register). If VS and VSINT decrease below VOVBR,cfgx,r - VHYS,cfgx (x = 0 to 7), then all low-sides MOSFETs are turned-off within tOFF_BRAKE after the filter time tOV_BR_FILT. If (VSHx - VSL) exceeds the config ured threshold, then all low-side s MOSFETs are turned-off within tOFF_BRAKE after the filter time tFVDS_BRAKE. The threshold is:

  • VVDSMONTH0_BRAKE if VDSTH_BRK = 0
  • VVDSMONTH1_BRAKE if VDSTH_BRK = 1

10.10 Current sense amplifier

The current sense amplifier (CSA) allows current meas urements with external shunt resistor in low-side configuration. The CSA is supplied by the charge pump (CP). Therefore, if the CP i s o f f , t h e n t h e C S A i s deactivated.

10.10.1 Unidirectional and bidirectional operation

The current sense amplifier (CSA) can work either as unid irectional or bi-directional operation. Refer to CSA register. Unidirectional operation CSD = 0

Datasheet 108 Rev. 1.0 2021-01-21 In unidirectional operation, the CS A is optimized to measure the curren t flowing through the external shunt resistor when VCSAP ≥ VCSAN. VCSO = VREF Unidir + (VCSAP - VCSAN + VOS) × GDIFF provided that VCSO is in the linear range1) 2). Bidirectional operation CSD = 1 In bidirectional operation, the CSA measures the current flow ing through the external shunt resistor in both directions: VCSAP ≥ VCSAN or VCSAP ≤ VCSAN. The output CSO works at half-scale range: VCSO = VREF Bidir+ (VCSAP - VCSAN + VOS) × GDIFF, provided that VCSO is in the linear range 2).

10.10.2 Gain configuration

The gain of the current sense amplifier is configurable by the configuration bits CSAG bits. Refer to Table 32.

10.10.3 Overcurrent Detection

A comparator at CSO detects overcurrent conditions. The overcurrent threshold is configurable with the OCTH bits. Refer to Table 33 for unidirectional operation and Table 34 for bidirectional operation. 1) Valid if 0.5 V ≤ VCSO ≤ VCC1 - 0.5 V. 2) VCSO is clamped between VCC1 and GND.

Datasheet 110 Rev. 1.0 2021-01-21 Figure 55 Overcurrent detection thresholds in bidirectional operation (CSD = 1) It is possible to program the device behavior when an overcurrent condition is detected:

  • OCEN bit = 0 (see CSA): the device only reports the over current event ( bit is set), without any change of the gate driver states.
  • OCEN bit = 1 (see CSA): the device reports the overcurr ent event ( bit is set) and actively turns off all MOSFETs with static discharge curent: – The MOSFETs can be reactivated by clearing OC_CSA or by resetting the OCEN bit. The overcurrent filter time is configurable (refer to tFOC) by the OCFILT control bits. tFOC refers to the output of the current sense amplifier. The CSO settling time (2 µs max, tSET) and the analog propagation delay (< 1 µs) are not taken into account by the overcurrent filter time.

10.10.4 CSO output capacitor

The capacitor connected to CSO (CCSO) must be between 10 pF and 2.2 nF. The control bit CSO_CAP optimizes the current consumption for CCSO < 400 pF or 400 pF < CCSO < 2.2 nF1).

Datasheet 119 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Serial Peripheral Interface

11 Serial Peripheral Interface

The Serial Peripheral Interface is the communication link between the device and the microcontroller. The TLE9185QX is supporting multi-slave operation in full-duplex mode with 32-bit data access. The SPI behavior for the different device modes is as follows:

  • The SPI is enabled in Init Mode, Normal Mode and Stop Mode.
  • The SPI is OFF in Sleep Mode, Restart Mode and Fail-Safe Mode.

11.1 SPI Block Description

The Control Input Word is read via the data input SDI, which is synchronized with the clock input CLK provided by the microcontroller. The output word appears synchronously at the data output SDO (see Figure 56 with a 32-bit data access example). The transmission cycle begins when the chip is selected by the input CSN (Chip Select Not), LOW active. After the CSN input returns from LOW to HIGH, the word that has been read is interpreted according to the content. The SDO output switches to tristate status (high impeda nce) at this point, thereby releasing the SDO bus for other use.The state of SDI is shifted into the input regist er with every falling edge on CLK. The state of SDO is shifted out of the output register after every rising ed g e o n C L K . T h e S P I o f t h e d e v i c e i s n o t d a i s y c h a i n capable.

11.2 Failure Signalization in the SPI Data Output

When the microcontroller sends a wrong SPI command to the device, the device ignores the information. Wrong SPI commands are either invalid device mode commands or commands whic h are prohibited by the state machine to avoid undesired device or system states (see below). In this case the diagnosis bit SPI_FAIL is set and the SPI Write command is ig nored (no partial interpretation). This bit can be only reset by actively clearing it via a SPI command. Invalid SPI Commands leading to SPI_FAIL are listed below (in this case the SPI command is ignored):

  • Illegal state transitions: - Going from Stop Mode to Sleep Mode. In this case the device enters Restart Mode. - Trying to go to Stop Mode or Sleep Mode from Init Mode1). In this case Normal Mode is entered.
  • Uneven parity in the data bit of the WD_CTRL register. In this case the watchdog trigger is ignored and/or the new watchdog settings are ignored respectively.
  • In Stop Mode: attempting to change any SPI settings, e.g. changing the watchdog configuration is ignored; only WD trigger, returning to Normal Mode, triggering a device soft reset, and read & clear status registers commands are valid SPI commands in Stop Mode; Note: No failure handling is done for the attempt to go to Stop Mode when all bits in the register WK_CTRL is cleared because the microcontroller can leave this mode via SPI.
  • When entering Stop Mode and WK_STAT is not cleared; SPI_FAIL will not be set but the INTN pin will be triggered.
  • Changing from Stop Mode to Normal Mo de and changing the other bits of the M_S_CTRL register. The other modifications will be ignored.
  • Sleep Mode: attempt to go to Sleep Mode without any wake source set, i.e. when all bits in the WK_CTRL register is cleared. In this case the SPI_FAIL bit is set and the device enters Restart Mode. Even though the Sleep Mode command is not entered in this case, the rest of the command is executed but restart values apply during Restart Mode; Note: At least one wake source must be activated in order to avoid a deadlock situation in Sleep Mode. If the only wake source is a timer and the timer is OFF, then the device will wake immediately from Sleep Mode and enter Restart Mode.
  • Setting a longer or equal on-time than the timer period of the respective timer.
  • SDI stuck at HIGH or LOW, e.g. SDI received all ‘0’ or all ‘1’. Note: There is no SPI fail in formation for unused addresses. Note: In case that the register or banking are access ed but they are not valid as address or banks, the SPI_FAIL is not triggered and the cmd is ignored. Signalization of the ERR Flag (high active) in the SPI Data Output (see Figure 56): The ERR flag presents an additional diagnosis possibility for the SPI communication. The ERR flag is being set for following conditions:
  • in case the number of receiv ed SPI clocks is not 0 or 32.
  • in case RSTN is LOW and SPI frames are being sent at the same time. 1) If the device is externally configured to use SPI with CRC (by PWM1/CRC pin), the attempt to go to Stop or Sleep from Init , will generate SPI_FAIL even if it is a SPI command with correct CRC. Still, the first SPI command will put the device from Init to Normal Mode even if CRC is not correct (CRC_FAIL status bit will be set).

Datasheet 121 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Serial Peripheral Interface Note: In order to read the SPI ERR flag properly, CLK must be low when CSN is triggered, i.e. the ERR bit is not valid if the CLK is high on a falling edge of CSN. The number of received SPI clocks is not 0 or 32: The number of received input clocks is supervised to be 0 or 32 clock cycles and the input word is discarded in case of a mismatch (0 clock cycle to enable ERR signalization). The error logic also recognizes if CLK was high during CSN edges. Both errors ( 0 or 32 bit CLK mismatch or CLK high during CSN edges ) are flagged in the following SPI output by a “HIGH” at the data output (SDO pin, bit ERR) before the first rising edge of the clock is received. The complete SPI command is ignored in this case. RSTN is LOW and SPI frames are being sent at the same time: The ERR flag will be set when the RSTN pin is triggered (during device restart) and SPI frames are being sent to the device at the same time. The behavior of the ERR flag will be signalized at the next SPI command for below conditions:

  • If the command begins when RSTN is HIGH and it ends when RSTN is LOW.
  • If a SPI command will be sent while RSTN is LOW.
  • If a SPI command begins when RSTN is LOW and it ends when RSTN is HIGH. And the SDO output will behave as follows:
  • Always when RSTN is LOW then SDO will be HIGH.
  • When a SPI command begins when RS TN is LOW and ends when RSTN is HIGH, then the SDO should be ignored because wrong data will be sent. Note: It is possible to quickly check fo r the ERR flag without sending any data bits. i.e. only the CSN is pulled low and SDO is observed - no SPI Clocks are sent in this case. Note: The ERR flag could also be set after the de vice has entered Fail-Safe Mode because the SPI communication is stopped immediately.

11.3 SPI Programming

For the TLE9185QX, 7 bits are used fo r the address selection (BIT 6...0). Bi t 7 is used to decide between Read Only and Read & Clear for the status bits, and betwee n Write and Read Only for configuration bits. For the actual configuration and status information, 16 data bits (BIT 23...8) are used. Writing, clearing and reading is done word wise. The SPI status bits are not cleared automatically and must be cleared by the microcontroller. Some o f t h e c o n f i g u r a t i o n b i t s w i l l a u t o m a t i c a l l y b e c l e a r e d b y t h e d e v i c e (refer to the respective register descriptions for detailed information). In Restart Mode, the device ignores all SPI communication, i.e. it does not interpret it. There are two types of SPI registers:

  • Control registers: These registers are used to configure the device, e.g. mode, watchdog trigger, etc.
  • Status registers: These registers indicate the status of the device, e.g. wake events, warnings, failures, etc. For the status registers, the requested information is given in the same SPI comma nd in the data out (SDO). For the control registers, the status o f e a c h b y t e i s s h o w n i n t h e s a m e S P I c o m m a n d a s w e l l . H o w e v e r , configuration changes of the same register are only shown in the next SPI command (configuration changes inside the device become valid only after CSN changes from low to high). See Figure 57. Writing of control registers is possible in Init and Normal Mode. During Stop Mode only the change to Normal Mode and triggering the watchdog is allowed as well as reading and clearing the status registers. No status information can be lost, even if a bit change s right after the first 7 SPI clock cycles before the SPI frame ends. In this case the status information field will be updated with the next SPI command. However, the flag is already set in the relevant status register.The device status information from the SPI status registers is transmitted in a compressed format with each SPI response on SDO in the so-called Status Information Field register (see also Table 36). The purpose of this register is to qu ickly signal changes in dedicated SPI status registers to the microcontroller. Table 36 Status Information Field Bit in Status Information Field Corresponding Address Bit Status Register Description

0 SUPPLY_STAT = OR of all bits on SUP_STAT register

1 TEMP_STAT = OR of all bi ts on THERM_STAT register

3 WAKE_UP = OR of all bits on WK_STAT register

5 DEV_STAT = OR of all bits on DEV_STAT except

CRC_STAT and SW_DEV

6 BD_STAT = OR of all bits on DSOV register

7 SPI_CRC_FAIL = (SPI_FAIL) OR (CRC_FAIL)

11.3.1 CRC

The SPI interface includes also 8 Bits (bits 24 to 31) used for Cyclic Re dundancy Check (CRC) to ensure data integrity on sent or received SPI command. The implemented CRC is based on Auto sar specification of CRC Routines re vision 4.3.0 and in particular the function CRC8-2FH. The specification are based on the follow table: Some examples of CRC calculation are shown in the follow table: Table 37 CRC8x2FH definition CRC result width: 8 bits Polynomial 2F H Initial Value FF H Input data reflected No Result data reflected No XOR value FF H Check DF H Magic check 42 H Table 38 CRC8x2FH calculation example Data Bytes (hexadecimal) CRC 00 00 00 00 12 F2 01 83 C2 0F AA 00 55 C6

The content of SDO Payload (BIT 8..23) is referring the previous data written at the addressed register via SDI. Figure 58 CRC calculation CRC Activation and status information For CRC activation, refer to Chapter 5.2. The CRC status (CRC_STAT)and failure (CRC_FAIL) are readable on DEV_STAT. Read out of the regist er which contains the CRC_STAT and CRC_FAIL is done ignoring the CRC field and no failure flag are set. The DEV_STAT register shall be cleared considering the CRC setting (ON or OFF). The CRC_STAT bit is read only. The CRC_FAIL is set in the follow conditions:

  • If the CRC is enabled and the µC sends wrong CRC field.
  • If the CRC is disabled and the µC sends wrong static pattern (no A5H). CRC field in case of CRC disabled In case that the CRC is not activated, the bits needed for CRC field have to be filled with static pattern. In case of SDI, the CRC field has to be filled with A5H (bits 24:31). In case of SDO, the device will always answer with 5AH (bits 24:31). The status of the CRC is updated accordingly in CRC_STAT bit. Add. r w Payload - Configuration CRC SDI ∑ PASS/FAIL Status Info. Field From previous SPI cmd CRC SDO

11.4 SPI Bit Mapping

The following figures show the mapping of the registers and the SPI bits of the respective registers. The Control Registers are Read/Write Register with the following structure:

  • Device Control Registers from 000 0001 B to 000 1011B.
  • Bridge Driver Control Registers from 001 0000 B to 001 1101B. Depending on bit 7 the bits are only read (setting bit 7 to ‘0’) or also written (setting bit 7 to ‘1’). The new setting of the bit after a write can be seen with a new read / write command. The Status Registers are Read/Clear with the following structure:
  • Device Status Registers from 100 0000 B to 100 0110B.
  • Bridge Driver Status Registers from 101 0000 B to 101 1011B.
  • Product Family is 111 0000 B. The registers can be read or can be cleared (if clearing is possible) depending on bit 7. To clear the payload of one of the Status Registers bit 7 must be set to 1. The registers WK_LVL_STAT, and FAM_PROD_STAT are an exception as they show the actual voltage level at the respective WKx pin (LOW/HIGH), or a fixed family/ product ID respectively and can thus not be cleared. It is recommended for proper diagnosis to clear respective status bits for wake events or failure. When changing to a different device mode, certain co n f i g u r a t i o n s b i t s w i l l b e cleared automatically or modified:
  • The device mode bits are updated to the actual status, e.g. when returning to Normal Mode.
  • When changing to a low-power mode (Stop Mode or Sleep Mode), the diagnosis bits of the integrated module are not cleared.
  • When changing to Stop Mode, the control bits will not be modified.
  • When changing to Sleep Mode, the control bits will be modified if they were not OFF or wake capable before. Note: The detailed behavior of the respective SPI bits and control functions is described in Chapter 11.5, Chapter 11.6.and in the respective module chapter. The bit type be marked as ‘rwh’ in case the device will modify respective control bits.

Datasheet 126 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Serial Peripheral Interface Figure 59 SPI Register Mapping Structure The detailed register mappings for control registers and status registers are shown in Table 39 and Table 61 respectively.

11.4.1 Register Banking

In order to minimize the number of configuration registers, seven registers follow a bank structure. The banked registers are:

  • WK_CTRL
  • CCP_BLK
  • TPRECHG
  • HB_ICHG
  • HB_PCHG_INIT
  • TDON_HB_CTRL
  • TDOFF_HB_CTRL In these register, the first 3 bits of the payload (bit 8 to 10) select the bank that has to be configured. The rest of the payload is used to configure the selected bank (for more details refer to the specific banked register). In case that CRC is used, the CRC calculation is done considering the first 24 bits (from bit 0 to 23). The banked registers can be read like the other configuration registers but in the SDO one ‘0’ is automatically added after the status information field. Figure 60 shows the structure of SDO in banked register. 7 Address Bits [bits 6...0] for Register Selection 16 Data Bits [bits 23...8] for Configuration & Status Information Reg.

11.5 SPI control registers

READ/WRITE Operation (see also Chapter 11.3):

  • The ‘POR / Soft Reset Value’ defines the re gister content after POR or device reset.
  • The ‘Restart Value’ defines the register content after device restart, where ‘x’ means the bit is unchanged.
  • There are different bit types: – ‘r’ = READ: read only bits (or reserved bits). – ‘rw’ = READ/WRITE: readable and writable bits. – ‘rwh’ = READ/WRITE/Hardware: readable/writable bits , which can also be modified by the device hardware.
  • Reserved bits are marked as “Reserved” and always read as “0”. The respective bits shall also be programmed as “0”.
  • Reading a register is done word wise by setting the SPI bit 7 to “0” (= Read Only).
  • SPI control bits are in general not cleared or ch anged automatically. This must be done by the microcontroller via SPI programming. Exceptions to this behavior are stated at the respective register description and the respective bit type is marked with a ‘h’ meaning that the device is able to change the register content. The registers are addressed wordwise.

11.6 SPI status information registers

READ/CLEAR Operation (see also Chapter 11.3):

  • One 32-bit SPI command consist of four bytes: - The 7-bit address and one additional bit for the register access mode and - following the two data bytes and the CRC. The numbering of following bit definitions refers to the data byte and correspond to the bits D0...D7 and to the SPI bits 8...23 (see also figure).
  • There are two different bit types: - ‘r’ = READ: read only bits (or reserved bits). - ‘rc’ = READ/CLEAR: readable and clearable bits.
  • Reading a register is done word wise by setting the SPI bit 7 to “0” (= Read Only).
  • Clearing a register is done word wise by setting the SPI bit 7 to “1”. No single bits can be cleared. Therefore the content of a SPI message (bit 8..23) doesn’t matter.
  • SPI status registers are in general not cleared or changed automatically (an exception are the x bits). This must be done by the microcontroller via SPI command. The registers are addressed wordwise.

Datasheet 165 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Serial Peripheral Interface Notes 1. The VCC1 undervoltage prewarning threshold V PW,f / VPW,r is a fixed threshold and independent of the VCC1 undervoltage reset thresholds. 2. VSINT undervoltage monitoring is not available in Stop Mode due to current consumption saving requirements. Exception: VSINT undervoltage detection is also available in Stop Mode if the VCC1 load current is above the active peak threshold (I_PEAK_TH) or if VCC1 is below the VCC1 prewarning threshold (VCC1_WARN is set). 3. The MSB of the POR/Soft Reset value is marked as ‘y’: the default value of the POR bit is set after Power-on reset (POR value = 1000 0000). However it will be cleared after a device Soft Reset command (Soft Reset value = 0000 0000). 4. During Sleep Mode, the bits V CC1_SC, VCC1_OV and VCC1_UV will not be set when VCC1 is off. 5. The VCC1_UV bit is never updated in Re start Mode, in Init Mode it is only updated after RSTN was released, it is always updated in Normal Mode and Stop Mode, and it is always updated in any device modes in a VCC1_SC condition (after VCC1_UV = 1 for > 2 ms).

Datasheet 168 Rev. 1.0 2021-01-21 TLE9185QX BLDC Driver Serial Peripheral Interface Notes 1. The bits DEV_STAT show the status of the device before exiting Restart Mode. Either the device came from regular Sleep Mode or a failure (Restart Mode or Fail-Safe Mode) occurred. Coming from Sleep Mode will also be shown if there was a trial to enter Sleep Mode without having cleared all wake flags before. 2. The WD_FAIL bits are implemented as a counter and are the only status bits, which are cleared automatically by the device. 3. The SPI_FAIL bit can only be cleared via SPI command. 4. The bit CRC_STAT and CRC_FAIL can be read regardless the CRC setting. The SPI read command on DEV_STAT ignores the CRC field.
