A5941
Overview
The A5941 three-phase motor driver incorporates sinusoidal drive to minimize audible noise and vibration for mediumpower fans. A sinusoidal voltage profile is applied to the windings of the motor at startup to quietly start and gradually ramp up the motor to the desired speed.
- AEC-Q100 qualified (K version)
- Quiet startup
- 180° sinusoidal drive for low audible noise
- High-efficiency control algorithm
- Sensorless operation
- Wide supply voltage range
- FG speed output
- Lock detection
- Overcurrent protection
- Soft start
