AH284 Datasheet (ETC) - Hall-Effect Smart Fan Motor Controller

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
