AH284 Hall-Effect Smart Fan Motor Controller

AH284 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary 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 th.
