The STMicroelectronics H-bridge gate driver is designed to drive 4 external N-channel MOS transistors for DC-motor driving in automotive applications. A free configurable current sense amplifier is integrated. The integrated standard serial peripheral interface (SPI) controls the device and provides diagnostic information. An interface pin for the thermal sensors of the external MOSFETs is implemented. Operating supply voltage 6 V to 28 V
Central 2-stage charge pump
100% duty cycle
Full RDS on down to 6 V (standard level threshold MOSFETs)
Charge pump output available for driving an external reverse battery NMOSFET protection
Charge pump current limited
Zero adjust for end of line trimming
Power management is programmable free wheeling
Sensing circuitry of external MOSFETs with embedded thermal sensors
