A5941 Product details

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.

Features

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.
Short-circuit protection.
