  • Logic level P-N gate drive (P high-side, N low-side).
  • 4.2 to 50 V supply range.
  • Simple block commutation for maximum torque.
  • Sensorless (bemf sensing) startup and commutation.
  • Programmable operating modes:.
  • Integrated speed control.
  • PWM duty cycle control.
  • Current mode control.
  • Cross-conduction prevention.
  • Wide speed range capability.
