A5944 General Description

The A5944 three-phase motor drivers incorporate sinusoidal drive to minimize audible noise and vibration for medium power 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 desired speed. The voltage profile is se.
