Motor Drivers

5.5 V to 45 VSPIexternal NMOSH-bridge gate driverAEC-Q100VQFN-32

DRV8703QRHBRQ1 is a 5.5 V to 45 V automotive H-bridge gate driver for four external N-channel MOSFETs, with SPI configuration, current sensing, PWM current regulation, and protection features.

Best for

  • Automotive brushed-DC motor H-bridges
  • Power-window, seat, sunroof, and sliding-door actuators
  • External MOSFET motor stages requiring SPI diagnostics

Avoid if

  • An integrated power MOSFET motor driver is required
  • The system supply is outside 5.5 V to 45 V
  • Independent half-bridge operation must include internal current chopping

Check before use

  • Validate MOSFET gate charge at the highest PWM or chopping frequency
  • Set VDS overcurrent monitoring for the selected MOSFET RDS(on) and expected current
  • Place VM, VCP, CPH/CPL, AVDD, and DVDD capacitors close to the device
