5 MOSFET Driver
5.1 Inputs and Dead Time
There are 6 independent control inputs to control the 6 MOSFETs individually. However, the control inputs for the High Side MOSFETs IHx are inverted. Hence, the control inputs for High Side IHx and Low Side MOSFETs ILx of the same half bridge can be tight together to control one half bridge by one control signal. To avoid shoot through currents within the half bridges, a dead time is provided by the TLE7184F-3V. For more details about the dead time please see Chapter 9.2.9
5.2 Output Stages
The 3 low side and 3 high side powerful push-pull output stages of the TLE7184F-3V are all floating blocks. All 6 output stages have the same output power and thanks to the bootstrap principle used, all MOSFETs can be switched all up to high frequencies. Each output stage has its own short circuit detection bl ock. For more details about short circuit detection see Chapter 9.2.10.1) Figure 3 Block Diagram of Driver Stages including Short Circuit Detection 1) The high side outputs are not designed to be used for low side MOSFETs; the low side outputs are not designed to be used for high side MOSFETs GHx SHx VDH VSCP Level shifter Floating HS driver 3x GLx SL VSCP Level shifter Floating LS driver 3x VREG Voltage regulator BHx VREG ___ INHVS Error logic Reset Power On Reset ____ ERR short circui t fi lter SCD SCD SCD Input Logic Shoot Through Protection Dead Time lock / unloc k ___ IH1 IL1___ IH2 IL2 ___ IH3 IL3 ON / OFF ON / OFF GND DT Short Circuit Detection Level ____ RGS SCDL VDH VREG blanking

5.3 Bootstrap Principle
The TLE7184F-3V provides a bootstrap based supply for its high side output stages. The benefit of this principle is a fast switching of the high side switches - supporting active freewheeling in high side. The bootstrap capacitors are charged by switching on th e external low side MOSFETs connecting the bootstrap capacitor to GND. Under this condition the bootstrap capacitor will be charged from the VREG capacitor. If the low side MOSFET is switched off and the high side MOSFET is switched on, the bootstrap capacitor will float together with the SHx voltage to the supply voltage of the bridge. Un der this condition the supply current of the high side output stage will discharge the bootstrap capacitor. This cu rrent is specified. The size of the capa citor together with this current will determine how long the high side MOSFET can be kept on without recharging the bootstrap capacitor. When all external MOSFETs are switched off, the SHx voltage can be undefined. Under this condition, the bootstrap capacitors can be discharged, dependent on the SHx voltage.
5.4 Currents at SH pins
The currents at the SH pins can be used for diagnostic purposes to check the health state of the power stage. The simplified structure related to the SH currents the TLE7184F-3V is described by Figure 4. Figure 4 Block Diagram of SHx pin configuration

Datasheet 16 Rev.1.2, 2016-01-27 TLE7184F-3V Shunt Signal Conditioning
6 Shunt Signal Conditioning
The TLE7184F-3V incorporates a fast and precise operati onal amplifier for conditioni ng and amplification of the current sense shunt signal. The gain of the OpAmp is adjustable by external resistors within a range higher than 5. The usage of high gains in the application might be limited by required settling time and band width. It is recommended to apply a small offset to the OpAmp, to avoid operation close to the lower rail at low currents. The output of the OpAmp ISO is not short-circuit proof. In addition to the integrated operational amplifier, th e TLE7184F-3V incorporates a comparator to detect over current situations. The output voltage VISO is compared to a reference voltage VOCTH close to the upper rail of the 3.3V OpAmp supply (VDD). If VISO reaches this level an error is set.

8.1 PWM Interface (IFMA)
The TLE7184F-3V has an integrated interface supporting the typical PWM interface between a remote master ECU and the µC. The link to the external master ECU is a single wire communication based on the battery voltage and running typ. with about 10 to 400 Hz. The information is encoded in the duty cycle of the signal. This communication line requires a signal conditioning to connect to the on board µC. The integrated circuit supports the incoming data path. The outgoing data path is formed by external components Figure 9 Structure PWM Interface The integrated circuitry is described in Figure 9. The main task of this interface is level shifting and protection of the µC. The IFuC signal is following the IFMA signal, passing the duty cycle information from IFMA to the IFuC. The µC port is used as input and is listening to the IFuC signal. The voltage at IFMA is monitored. If IFMA is low the IFuC open drain output is switched on - forcing the IFuC signal to low. If IFMA is high, the IFuC open drain output is deactivated and the IFuC signal is pulled to high by the internal pull- up resistor. The IFMA input is used as well for wake-up. See Chapter 9.1 Influence of serial resistor at IFMA pin As shown in Figure 9 a 10k resistor R1 is recommended to protect the IFMA pin against negative voltage levels coming from the interface signal. The integrated pull do wn and pull up resistors at the IFMA pin form an voltage divider together with the resistor R1. Th is will influence the result ing switching level of th e IFMA interface in the application compared to the levels specified directly at the IFMA pin. In this datasheet an additional parameter is provided to calculate the influence of t he 10k resistor. The specified IFMA input current divided by Vs allows to calculate the drop over R1 with the following formula: uC Interface_uC GND TLE 7184 F KL 30 Pull up interface ECU VDD VCC IFuC IFMA Wake up 10k VS VS 700k 340k IRoverdropVoltage VS VS IFMA=

8.2 VDHS Switch
The System IC has an integrated switch connecting the VDH pin to the VDHS pin. This allows to place an external voltage divider for VDH voltage monitoring at the VDHS pin and to disconnect this voltage divider from VDH during sleep mode to assure low current consumption. The VD HS switch is only deactivated when the VDD regulator is switched off.
8.3 Digital Output INHD
The System IC provides a digital output INHD showing the logic state of INH (e.g. KL15) after a complete wake- up of the driver (approx. 1ms). The input levels of INH for the INHD output are defined separately from the levels for wake-up. Voltage levels for INH wake-up function please see Chapter 9.4 section Wake-up and go-to-sleep. The output stage consists of an integrated low side switch with a pull-up resistor to VDD.

Datasheet 24 Rev.1.2, 2016-01-27 TLE7184F-3V Description of Modes, Protection and Diagnostic Functions Sleep Mode: The sleep mode is entered if the device is in the Go-to-sleep Mode and the VDD voltage is lower than VDDsleep. The complete chip is deactivated beside the wake-up fu nction (see Wake-up Mode). This mode is designed for lowest current consumption from the po wer net of the car. The passive clamping is active. For details see the description of passive clamping, see Chapter 9.2.14. The only way to leave the Sleep Mode is to go to the Wake-up Mode. Wake-up Mode: The TLE7184F-3V wakes up if INH (=KL15) is high or if IFMA is low and VVS is higher than VVSLO. In this mode all supplies are ramping up. As soon as the internal 5V is available, a so called wake-up timer starts to run. If the IC reaches this state, the wake-up will continue even if the wake-up signals at INH or IFMA disappear. The PWM interface (IFMA) is active as soon as the VDD voltage is sufficiently high. During this time it is expected that the supplies are powered up and the µC sets the RGS to high. All external MOSFETs are switched off actively or passively. When the wake-up timer is expired the IC goes into the Error mode. In this mode all errors will be ignored beside Over Temperature Shut Down or VS Under Voltage Lockout. Error Mode The Error Mode can be reached in 2 different ways: 1. The device is in Wake-up Mode and the wake-up timer expires 2. The device is in Normal Mode and one or more of the following errors occur: VREG Under Voltage Shut Down, VDD Under Voltage Shut Down, Over Current Shut Down, VDH Over Voltage Shut Down, IOV Over Voltage Shut Down, Short Circuit Detection or SCDL Open Detection. In this mode an Error is set at the ERROR Pin and all external MOSFETs are actively switched off as long as the bootstrap voltages allows it. The interface is active. VDHS switch is on and the current sense functions are working. VDD and VREG are active. Passive clamping is not active. The Error mode can be left in the following ways: 1. If no error is present, the IC can be sent to Normal Mode by a reset with the RGS pin. 2. If a VREG Under Voltage Shut Down occurs the device will go to VREG Shut-down Mode. 3. If VDD Under Voltage Shut Down occurs the device will go into Deadlock Mode. Normal Mode The Normal Mode can be reached by: 1. The device is in Error Mode, no error is pr esent and a reset is performed by the RGS pin. In the Normal Mode all functions are active and available with the regular limitations of the bootstrap principle. The gate drive output stages can be controlled with the input pins. The Normal Mode can be left in 4 ways: 1. The devices goes to the Go-To-Sleep Mode by setting RGS to low for a time longer than tsleep. 2. If a VREG Under Voltage Shut Down occurs the device will go to VREG Shut-down Mode. 3. If VDD Under Voltage Shut Down occurs the device will go into Deadlock Mode. 4. If one or more of the following errors occur, the device goes to the Error Mode: VREG Under Voltage Shut Down, VDD Under Voltage Shut Down, Over Current Shut Down, VDH Over Voltage Shut Down, IOV Over Voltage Shut Down, Short Circuit Detection or SCDL Open Detection. Go-To-Sleep Mode The Go-To-Sleep Mode can be reached in 2 different ways: 1. The device is in Normal Mode and RGS is set to low for a time longer than tsleep. 2. The device is in VREG Shut-down Mode and RGS is set to low for a time longer than tsleep.
Description of Modes, Protection and Diagnostic Functions Datasheet 25 Rev.1.2, 2016-01-27 In this mode all external MOSFETs are actively or passively switched off. An Error is set and is shown as long as VDD is sufficient high. In this mode VDD and VREG is switched off. As soon as VDD voltage reaches the VVDDsleep level the IC goes into the Sleep Mode. Deadlock Mode This mode is intended to prevent the IC for long time toggling in Over Temperature if a short is present at the VDD pin. There are 3 ways to enter this mode: 1. The IC is in Error Mode and a VDD Under Voltage Shut Down occurs. 2. The IC is in Normal Mode and a VDD Under Voltage Shut Down occurs. 3. The IC is in VREG Shut Down Mode and a VDD Under Voltage Shut Down occurs. In this mode VDD and VREG regulators are switched o ff. The gates of the exter nal MOSFETs are passively clamped. The VDHS switch is deactivated. The IC will not react to IFMA or INH signals. Even a Over Temperature Shut Down detection will have no influence. The internal logic is supplied and prevents the IC from going into “Go-to-Sleep Mode”. The only way to leave this state is that VS is lower than VVSLO, means a VS Under Voltage Lockout occurs. In this case the IC goes to Sleep Mode. VREG Shut Down Mode This mode is intended to prevent the IC from long time toggling in Over Temperature if a short is present at the VREG pin. There are 2 ways to enter this mode: 1. The IC is in the Error Mode and a VREG Under Voltage Shut-down occurs. 2. The IC is in the Normal Mode and a VREG Under Voltage Shut-down occurs. In this mode VREG is switched off, but VDD is still present. The VDHS switch is still active and the PWM interface (IFMA) is working. The IC will not react to IFMA or INH signals. In this situation the µC is still able to provide diagnostic information by the interface. It can prevent the IC from Go- to-Sleep Mode and can avoid unintended toggling as long there is no Over Temperature Shut Down. This state can be left by 2 ways: 1. The µC has to set RGS to low for a time longer than tsleep. In this case the IC goes to Sleep Mode. 2. If a VDD Under Voltage Sh ut Down occurs the IC will go into the Deadlock Mode.
9.2 Protection and Diagnosis Functions
9.2.1 Over Temperatur e Shut Down (OTSD)
If the junction temperature is exceeding the Over Temperat ure shut down level an error signal is set. The driver IC will pull down the gate-source voltage of all external MOSFETs, deactivate the VDD and VREG supply and go directly into the Sleep Mode. In the Sleep Mode the regular wake-up conditions will be used. Over Temperature cycling is possible and will lead to accelerated aging of the IC. In Deadlock Mode an Over Temperature Shut Down is ignored.
Datasheet 26 Rev.1.2, 2016-01-27 TLE7184F-3V Description of Modes, Protection and Diagnostic Functions
9.2.2 Analog Temperature Monitoring
The TEMP output of the TLE7184F-3V provides an analo g voltage signal proportional to the chip temperature. This function is not available in Deadlock Mode.
9.2.3 VS Under Voltag e Lockout (VS_UVLO)
The TLE7184F-3V has an integrated VS Under Voltage Lockout to assure that the behavior of the complete IC is predictable in all supply voltage ranges. If the supply voltage at VS reaches the Under Voltage shut down level VVSLO for a minimum specified filter time the IC goes into Go-to-Sleep Mode and finally into Sleep Mode.
9.2.4 VDD Under Voltag e Diagnosis (VDD_UVD)
The TLE7184F-3V has an integrated VDD Under Voltage Diagnosis to assure that the behavior of the bridge driver output stages is predictable in all supply voltage ranges. If the voltage at VDD reaches the Under Voltage diagnosis level VUVVDD for a minimum specified filter time, an error is set and the IC goes into Error Mode. Figure 11 Timing of VDD Under Voltage Diagnosis
9.2.5 VDD Under Voltage Shut Down (VDD_UVSD)
The TLE7184F-3V has an integrated VDD Under Voltage Shut Down to avoid operation with VDD shorted to GND. If the supply voltage at VDD reaches the Under Voltage shut down level VVDDsleep and the wake-up time is expired, VREG and VDD will be switched off and the IC will go to the Deadlock Mode. VVDD VRT ERR TRR VS < TRR ____ RGS
Description of Modes, Protection and Diagnostic Functions Datasheet 27 Rev.1.2, 2016-01-27
9.2.6 VREG Under Voltag e Diagnosis (VREG_UVD)
The TLE7184F-3V has an integrated VREG Under Voltage Dia gnosis to assure that th e behavior of the bridge driver output stages is predictable in all supply voltage ranges. If the voltage at VREG reaches the Under Voltage diagnosis level VUVVR for a minimum specified filter time an error is set the IC goes into Error Mode. As long as the VS Under Voltage Lock Out is not reached, the low side MOSFETs will stay actively switched off. The status of the high side MOSFET drivers is depende nt on the bootstrap voltage - which depends on the SHx voltage. It is expected that the SHx nodes will be pulled to VDH level by the high side MOSFETs and this will switch off the high side MOSFETs passively. In this situation the short circuit detection of this output stage is deactivated to avoid wrong error reporting.
9.2.7 VREG Under Voltage Shut Down (VREG_UVSD)
The TLE7184F-3V has an integrated VREG Under Volta ge Shut Down to avoid oper ation with VREG shorted to GND. If the supply voltage at VREG reaches the Under Voltage shut down level VVRSD “AND” the wake up time is expired, VREG will be switched off and the IC will go to th e VREG Shut Down Mode. In this condition the µC is still supplied and can communicate via the PWM interface (IFMA), the MOSFETs are switched off and an error is set. The only way to leave this mode is to go to “Sleep Mode”.
9.2.8 IOV and VDH Over Voltage S hut Down (IOV_OVSD, VDH_OVSD)
The TLE7184F-3V has an integrated Over Voltage shut down to minimize the risk of destruction of the IC at high supply voltages caused by violation of the maximum ratings. The voltages are observed at the Over Voltage input pin IO V and at the VDH pin. If the voltage at the IOV pin or at the VDH pin exceeds the Over Voltage shut down level fo r more than the specified filter time, the IC goes into Error Mode. The effective Over Voltage level can be adjusted by a vo ltage divider at the IOV pin. This voltage devider is normally supplied by the VDHS pin. The Over Voltage level at VDH is fix.
9.2.9 Dead Time and S hoot Through Protection
In bridge applications it has to be assured that the exte rnal high side and low side MOSFETs are not “on” at the same time, connecting the battery voltage directly to GND. The dead time generated in the TLE7184F-3V is set to a minimum value if the DT pin is connected to GND. This function assures a minimum dead time if a common input signal for ILx and IHx is used. The dead time can be increased by connecting the DT pin via a dead time resistor RDT to GND. Larger dead time resistors result in a longer dead time. The typical dead time can be calculated with the following formula: Please put in the Rdt in kΩ. If an exact dead time of the bridge is needed, the use of the µC PWM generation unit is recommended. In case of an open DT pin, the dead time is set to the internal maximum value. In addition to this dead time, the TLE7184F-3V prov ides a locking mechanism avoiding that both external MOSFETs of one half bridge can be switched on at th e same time. This function ality is called shoot through protection. µst Rdt deadtime ++= 44.202.0 081.0
Datasheet 28 Rev.1.2, 2016-01-27 TLE7184F-3V Description of Modes, Protection and Diagnostic Functions If the command to switch on both high and low side switches in the same half bridge is given at the input pins, the command will be ignored. The outputs will stay in the state like before the conflicting input.
9.2.10 Short Circuit Protection (SCP)
The TLE7184F-3V provides a short circuit protection for the external MOSFETs. It is monitoring of the drain-source voltage of the external MOSFETs. (see Figure 3 ) The drain-source voltage monitoring for a certain external MOSFET is active as soon as the corresponding driver output stage is set to “on” and the dead time and the blanking time is expired. The blanking time starts when the dead time is expired and assures that the switch on process of the MOSFET is not taken into account. It is recommended to keep the switching times of the MOSFETs below the blanking time. The short circuit detection level is adjustable in an analogue way by the voltage setting at the SCDL pin. There is a 1:1 translation between the voltage applied to the SCDL pin and the drain-source voltage limit. E.g. to trigger the SCD circuit at 1 V drain-source voltage, the SCDL pin must be set to 1 V as well. The drain-source voltage limit In the case that after the expiration of the blanking time the drain source voltage of the observed MOSFET is still higher then the SCDL leve l, the SCD filter time tSCP starts to run. A capacitor is charged with a current. If the capacitor voltage reaches a specific level (filter time tSCP), the error signal is set and the IC goes into Error Mode. If the SCD condition is removed before the SC is detected, the capacitor is discharged with the same current. The discharging of the capacitor happens as well when the MOSFET is switched off. It has to be considered that the high side and the low side outputs of one phase are working with the same capacitor.
9.2.11 SCDL Pin Open Detection (SCDL_open)
For safety reasons a pull-up resistor at the SCDL pin assu res that in case of an open pin the SCDL voltage is pulled to a high level. In this case an error is set and the IC goes into Error Mode.
9.2.12 Over Current Shut Down (OCSD)
The TLE7184F-3V is monitoring the output signal of the operational amplifier. If the output signal reaches a specified level close to the upper rail (VDD) for a specifie d time, the System IC detects an over current condition and sets an error signal. The driver output pulls down the gate-source voltage of all external MOSFETs actively and stays in the Error Mode.
9.2.13 VDD Current Limitation
The TLE7184F-3V has an integrated voltage supply for an external µC. The output current of the supply is limited to a specified value. This limitation does not cause any error reporting. In this situation a VDD Under Voltage detection is likely. If the current is limited for a longer time, the Over Temperature protection will react.
9.2.14 Passive Gxx Clamping
If VS Under Voltage Lock Out is detected or the device is in Sleep Mode, a passive clamping is active as long as the voltage at VS or VDH is higher th an 3V. Even below 3V it is assured that the MOSFET driver stage will not switch on the MOSFET actively. The passive clamping means that the BHx and the VREG pin are pulled to GND with specified pull down resistors. Together with the intrinsic diode of the push stage of the output stages which connec t the gate output to BHx respectively VREG, this assures that the gate of the external MOSFETs are not floating.
9.3 E RR Pin
The TLE7184F-3V has a status pin to provide diagnostic fee dback to the µC. The logical output of this pin is an open drain output with integrated pull-down resistor to GND (see Figure 12).
