A5944 Product details

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.

Features

Sinusoidal drive for low audible noise.
Quiet startup adjustment feature.
High efficiency control algorithm.
Sensorless operation.
PWM speed input.
FG speed output.
Lock detection.
Short-circuit protection.
Standby mode.
