DESCRIPTION
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. The voltage...
