A5931: Three Phase Sensorless Fan Driver

The A5931 is a three phase sensorless BLDC fan driver IC that incorporates sinusoidal drive to minimize audible noise and vibration.

A flexible closed-loop speed control system is integrated into the IC. This eliminates the requirement for a microprocessor-based system and minimizes programming requirements.

The A5931 device is available in both commercial and automotive grade.
