A5932 - Three-Phase Sinusoidal Sensorless Fan Controller

General Description

The A5932 three-phase motor controller incorporates sinusoidal drive to minimize audible noise and vibration for high-power fans.

A sinusoidal voltage profile is applied to the windings of the motor at startup to quietly start up and gradually ramp up the motor to desired speed.

Key Features

  • Automotive grade, AEC-Q100 qualified.
  • Sinusoidal drive for low vibration and noise.
  • Configurable closed loop speed curves.
  • RD output.
  • Quiet startup.
  • Proprietary high-efficiency control algorithm.
  • Automatic phase advance.
  • Windmill detection.
  • Fault output.
  • FG speed output.
  • Lock detection.
  • Overcurrent limit (OCL).
  • Short-circuit protection (OCP).
  • Direction input.
  • Br.
