AH287 Description
AH287 is a monolithic fan motor controller with Hall sensor’s capability. It contains two plementary open-drain drivers for motor’s coil driving, automatic lock shutdown and restart function relatively. To avoid coil burning, rotor-lock shutdown detection circuit shut down the output driver if the rotor is blocked and then the automatic recovery circuit will try to restart the motor.
