A5940: Three Phase Sensorless Sinusoidal Fan Driver

Description

The A5940 three phase motor driver incorporates 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 startup and gradually ramp up the motor to desired speed. 

This device is available in both automotive and commercial grade.

Top Features

  • 180° sinusoidal drive - low audible noise and vibration
  • Motor position using Allegro's sensorless algorithm - eliminates external Hall sensors
  • AEC-Q100 Qualified - suitable for automotive applications
