Description
The BTN9960LV is an integrated high current half-bridge for motor drive applications. It is part of the MOTIX™ single half-bridge product family containing one p-channel high-side MOSFET and one n-channel low-side MOSFET with an integrated driver IC in one package. Due to the p-channel high-side switch the need for a charge pump is eliminated thus minimizing EME. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and short circuit. The BTN9960LV provides a cost optimized solution for protected high current PWM motor drives with very low board space consumption.

1 Block diagram
The BTN9960LV contains three separate chips in one package: one p-channel high-side MOSFET and one n-channel low-side MOSFET together with a driver IC, forming an integrated high current half-bridge. All three chips are mounted on a common lead frame, using the chip-on-chip and chip-by-chip technology. The power switches utilize vertical MOS technologies to ensure optimum ON-state resistance. Due to the p-channel high- side switch the need for a charge pump is eliminated thus minimizing EME. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, overcurrent, undervoltage and short circuit. The BTN9960LV can be combined with other BTN9960LVs to form an H-bridge or a 3-phase drive configuration.

4.2 Power stages
The power stages of the BTN9960LV consist of a p-channel vertical DMOS transistor for the high-side switch and a n-channel vertical DMOS transistor for the low-side switch. All protection and diagnostic functions are located in a separate driver IC. Both switches allow active freewheeling and thus minimizing power dissipation during PWM control. The ON-state resistance RON is dependent on the supply voltage VS as well as on the junction temperature Tj.

4.3 Protection functions
The device provides integrated protection functions. These are designed to prevent IC destruction under fault conditions described in the datasheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not designed to be used for continuous or repetitive operation, with the exception of Undervoltage, overtemperature and overcurrent events are indicated by a fault current IIS(fault) at the IS pin as described in Chapter 4.4.3. The protection functions of the BTN9960LV are prioritized in the following way: Table 8 Protection functions priorities Priority Function Reference 0 (highest) Undervoltage shutdown Chapter 4.3.1 1 Overtemperature protection Chapter 4.3.2 2 Overcurrent protection Chapter 4.3.3
3 Stand-by mode The device only goes into stand-by mode if no fault is present
Datasheet 16 Rev. 1.00 2023-03-01
4.3.1 Undervoltage shutdown with restart
To avoid uncontrolled motion of the driven motor at low voltages the device switches off (output is tri-state), if the supply voltage drops below the switch-OFF voltage VUV(OFF). If a slew rate level SR0 to SR4 is selected, the device will switch off with the selected slew rate in case of an undervoltage detection. For slew rate level SR5 to SR7, the device will switch off with slew rate level SR4 instead. As soon as the supply voltage VS rises above the switch-ON voltage VUV(ON), with a hysteresis of VUV(HY), the output channel of the device follows the IN pin again. The restart is delayed with a time tUVD which protects the device in case the undervoltage condition is caused by a short circuit event (according to AEC-Q100-012). After power-up, the device is starting without waiting for the delay time tUVD. The slew rate level and the undervoltage event are stored in analog latches, which are supplied by the INH or/and IN pin. Thus at least one of the two pins always shall be set high during this undervoltage event, until the presence of the IIS(fault) current, to keep the previously set slew rate level after the undervoltage shutdown. In the case of both INH and IN being 0 during an undervoltage event, a power on reset is performed. In case of an undervoltage event, the fault current IIS(fault) is provided at the IS pin, once the supply voltage rises above VUV(ON) again. The fault signal at the IS pin is reset after tUVD after the supply voltage rises above VUV(ON). This behavior is shown in Figure 9. I IS(fault) t V UV(ON) V UV(OFF) V UV(HY) t V OUT V S INH t IN t t I IS t UVD Current sense (CS)CSCS Figure 9 Timing diagram for undervoltage behavior for load to GND
4.3.2 Overtemperature protection
The device is protected against overtemperature by an integrated temperature sensor. Overtemperature leads to a shutdown of the output stage (both the high-side and low-side switch). This state is latched until the device is reset by a low signal with a minimum length of treset at the INH and IN pin, provided that its temperature has decreased at least the thermal hysteresis ΔT in the meantime. BTN9960LV Datasheet Datasheet 17 Rev. 1.00 2023-03-01
If a slew rate level SR0 to SR4 is selected, the device will switch off with the selected slew rate in case of overtemperature. For slew rate level SR5 to SR7, the device will switch off with slew rate level SR4 instead.
4.3.3 Overcurrent protection
The current in the bridge is measured in both switches. As soon as the current in forward direction in one switch (high-side or low-side) is reaching the limit IOCx, the device goes either into current limitation mode or switches off with latch, depending on the selected SR-level. The corresponding dependencies are described in Table 9. Table 9 Slew rate dependent overcurrent strategies SR-level Mode Note SR0 Current limitation (retry) For details see Chapter 4.3.3.1 SR1 SR2 SR3 SR4 SR5 Switch-OFF with latch Requiring reset of the fault latch For details see Chapter 4.3.3.2SR6 SR7
4.3.3.1 Current limitation
If this mode is selected according to Table 9 and the current in forward direction in one switch (high-side or low-side) has reached the limit IOCx, the affected switch is deactivated and the other switch is activated for tCLS. During that time all changes at the IN pin are ignored. However, during current limitation, the INH pin can still be used to switch both MOSFETs off. After tCLS the switches follow the IN pin again. The fault signal at the IS pin is reset after 1.5 * tCLS. This behavior is shown in Figure 10. t t I IS I OCx0 I L t CLS 1.5 × t CLS I IS(fault) I OCx Figure 10 Timing diagram current limitation (inductive load) For this mode, the MOSFETs are switched off each with the same slew rates (SR-level) as in normal operation. BTN9960LV Datasheet Datasheet 18 Rev. 1.00 2023-03-01
In combination with a typical inductive load, such as a motor, this results in a switched mode current limitation. This method of limiting the current has the advantage of greatly reduced power dissipation in the BTN9960LV compared to driving the MOSFET in linear mode. Therefore it is possible to use the current limitation for a short time without exceeding the maximum allowed junction temperature (e.g. for limiting the inrush current during motor start up). However, the regular use of the current limitation is allowed as long as the specified maximum junction temperature is not exceeded. Exceeding this temperature can reduce the lifetime of the device.
4.3.3.2 Switch-OFF with latch
If this mode is selected according to Table 9 and as soon as the current in forward direction in one switch (high-side or low-side) has reached the limit IOCx, both output stages are shut down. This state is latched until the device is reset by a low signal with a minimum length of treset at the INH and IN pin. This behavior is illustrated in Figure 11. In order to minimize power dissipation, the MOSFETs are switched off each with the same slew rate level SR4.

4.3.4 Short circuit protection
The device provides embedded protection functions against
- Output short circuit to ground
- Output short circuit to supply voltage
- Short circuit of load The short circuit protection is realized by the previously described undervoltage and overcurrent protection in combination with the overtemperature shutdown of the device.

4.4 Control and diagnostics
The control inputs IN and INH consist of TTL/CMOS compatible Schmitt triggers with hysteresis which control the integrated gate drivers for the MOSFETs. Setting the INH or/and IN pin to high enables the device. When the INH pin is high, one of the two power switches is switched on depending on the status of the IN pin. To deactivate both switches, the INH pin has to be set to low. No external driver is needed. The BTN9960LV can be interfaced directly to a microcontroller, as long as the maximum ratings in Chapter 3.1 are not exceeded.
4.4.1 Dead time generation
In bridge applications it has to be assured that the high-side and low-side MOSFET are not conducting at the same time, connecting directly the battery voltage to GND. This is assured by a circuit in the driver IC, generating a so called dead time between switching off one MOSFET and switching on the other. The dead time generated in the driver IC is dependent on the selected slew rate.
4.4.2 Adjustable slew rate
In order to optimize electromagnetic emission, one of 8 different switching speeds for the MOSFETs can be selected. This selectability allows the user to optimize the balance between emission and power dissipation within his own application. The slew rate adjustment function is only accessible, if no fault is present. BTN9960LV Datasheet Datasheet 20 Rev. 1.00 2023-03-01
In case the device was in stand-by mode previously, the function is available after the device wake-up time twakeup. Therefore the first pulse at pin IN needs to exceed the wake-up time twakeup. When INH = low and IN = high without a fault being present, the device is in SR selection mode with both high-side and low-side MOSFETs being switched off. When the SR selection mode initially is entered, a temperature information is provided as described in Chapter 4.4.3.2 at the IS pin independently from the selected SR-level. Only when IN goes low (falling edge) for a duration of tSR, the next mode is selected when IN rises again. During this transition pulse, the INH pin has to be low permanently. In the next mode, the slew rate won’t be changed, but a current sense signal IIS(SRx) depending on the currently selected SR-level SRx (as further described in Chapter 4.4.3.2) is provided at the IS pin. This allows to validate if the desired SR-level has been selected. For any further transition pulse, the next SR-level will be selected. The newly selected SR-level then will be indicated at the IS pin with the corresponding IIS(SRx). After reaching SR-level SR7, the next selectable SR-level is SR0 again. This procedure is illustrated in Figure 12. The SR selection mode is left if a fault occurs or by setting INH to high. The procedure is shown in the state diagram in Figure 15. The states at pin IN and INH may not transition synchronous in the same direction, therefore a time delay of tlag need to be applied. After stand-by and power-up, the default value for the slew rate is level SR0. After an undervoltage event the selected slew rate level is persistent, under the conditions described in Chapter 4.3.1 with more details. In case an undervoltage event occurs during the slew rate selection mode, the slew rate configuration can not be guaranteed. Therefore slew rate programming need to be repeated once the undervoltage event has disappeared.

4.4.3 Status flag diagnosis with current and temperature sense capability
The sense pin IS is used as a combined current sense, temperature sense, slew rate level feedback and fault flag output. Further details, in which state which signal is provided by the IS pin is described in Table 11. The IS pin has three different modes of operation:
4.4.3.1 Current sense
In normal operation (current sense mode), with the IN and INH pin being high (for further details see Table 11), a current source is connected to the IS pin, which delivers a current proportional to the forward load current flowing through the active high-side switch. The sense current can be calculated out of the load current by the following equation: IIS = IL / dkILIS + IIS(offset) BTN9960LV Datasheet Datasheet 21 Rev. 1.00 2023-03-01
The other way around, the load current can be calculated out of the sense current by following equation: IL = dkILIS · (IIS – IIS(offset)) The differential current sense ratio dkilis is defined by: dkILIS = (IL2 – IL1) / (IIS(IL2) – IIS(IL1)) If the high-side drain current is zero (ISD(HS) = 0 A) the offset current IIS = IIS(offset) still will be driven. The external resistor RIS determines the voltage per IS output current. The voltage can be calculated by VIS = RIS · IIS.

4.4.3.2 Temperature sense and slew rate feedback
In slew rate selection mode, with the IN pin being high and the INH being low after the first transition (further details see Chapter 4.4.2) the IS pin provides a constant current IIS(SRx), allowing to distinguish between the different SR-levels. The sense current IIS can be calculated as follows for the slew rate level SRx: IIS(SRx) = IIS(SR0) – x ⋅ IIS(SR_step) To correctly determine all eight slew rate levels, IIS(SR0) and each individual device's IIS(SR_step) have to be calibrated. When initially entering the SR selection mode, a current source is connected to the IS pin, which delivers a current proportional to the junction temperature of the control chip TCC, which is illustrated in Figure 14. The sense current IIS(T) can be calculated out of the junction temperature in Kelvin T[K] by the following equation: IIS(T) = kTIS · TCC Based on the temperature coefficient kTIS, the temperature TCC then calculates as follows: TCC = IIS(T) / kTIS BTN9960LV Datasheet Datasheet 22 Rev. 1.00 2023-03-01

4.4.3.3 Fault feedback
In case of a fault condition, according to the truth table (Table 11), the status output is connected to a current source which is independent of the load current and provides IIS(fault). The maximum voltage at the IS pin is determined by the choice of the external resistor and the supply voltage.

The function must be verified in the real application. To stabilize the supply voltage VS in PWM operation or in over current limitation a sufficient dimensioned low ESR electrolytic capacitor CDC-Link is needed. It prevents destructive voltage peaks and drops. The supply voltage ripple at the device between VS pin and GND must be kept below 1 V peak-to-peak and the capacitors need to be sized accordingly. Therefore the ceramic capacitors C10/C11 respectively C20/C21 must be placed close to the device pins VS and GND. The traces should be kept as short as possible to minimize stray inductance. The value of the capacitors must be verified in the real application to ensure low ripple and transients at the VS pin. The digital inputs IN and INH need to be protected against over-currents (e.g. caused by induced voltage spikes) by a series resistor of typical 1 kΩ.
