Three Phase - Bridges

ST’s fully-integrated drivers combine all the circuitry needed for 3-phase brushless DC motors.

Key benefits include:

  • Integrated 3-phase DMOS bridge, constant off-time PWM controller, and decoding logic for single-ended Hall sensors that generate the required sequence for the power stage
  • Full set of protection features to further reduce the number of external components, the cost and complexity
  • Independent current senses for field oriented control applications
