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
