    Key features
    Key features
    • AEC-Q100 qualified
    • RoHs compliant device
    • Power supply operating range from 4.51 V to 28 V (gate drivers operative from 5.41 V)
    • 3.3 V/5 V compatible I/Os
    • All pins linked to the microcontroller, fail-safe input and VDD are made tolerant to battery exposure
    • Dual half-bridge driver compatible with standard level threshold NMOSFETs
    • Configurable full-bridge or dual independent half-bridges control
      • Programmable recirculation path in case of full-bridge control
    • Dual stage charge pump supporting 100% PWM duty cycle down to 5.41 V battery voltage
      • High and low side minimum VGS=6.2 V @ VDH=5.5 V and charge pump load current (ICPLOAD) equal to 5 mA
      • High and low side minimum VGS=8.2 V @ VDH≥8 V and charge pump load current (ICPLOAD) equal to 10 mA
    • Charge pump output available for driving an external reverse battery NMOSFET protection
    • Programmable gate driving current (up to 170 mA) for output voltage slew rate control
    • Programmable drain-source monitoring for overcurrent protection and programmable cross-current protection time (dead-time)
    • Open load and output short circuit detection in off-state diagnostic mode
    • SPI for control and diagnosis (ST SPI 4.1)
    • Programmable diagnostic output
    • Two independent current sense amplifiers
      • Low offset with extremely low thermal drift
      • Suitable for high-side, in-line and low–side current sensing
      • Independently programmable gain (10x, 20x, 50x, 100x)
      • Analog output centered at VDD/2 or VDD/22
    • Overtemperature prewarning and shutdown
    • Analog and digital power supply inputs over/undervoltage protections
    • Asynchronous and logic independent fail-safe input to switch off all the MOSFETs
    • Low quiescent current
    • Support for random HW faults up to ASIL B
