DRV8889QPWPRQ1 is an AEC-Q100 bipolar stepper driver for automotive actuators, integrating current sensing, dual H-bridges, microstepping, SPI diagnostics, and stall detection.

Best for

  • AEC-Q100 automotive stepper motor actuators
  • Headlamp leveling mechanisms
  • HVAC and display positioning systems

Avoid if

  • Applications requiring more than 1.5 A full-scale current per bridge
  • Motor supply rails outside 4.5 V to 45 V
  • Designs without adequate thermal copper and exposed-pad grounding

Check before use

  • Validate motor RMS current against thermal limits
  • Select and test the PWM decay mode
  • Review SPI fault reporting and reset behavior
  • Use the recommended VM, VCP, CPH/CPL, and DVDD capacitors
