AH285 Datasheet (Anachip) - Hall-Effect Smart Fan Motor Controller

AH285, Hall-Effect Smart Fan Motor Controller

AH285 is a monolithic fan motor controller with Hall sensor’s capability.

It contains two complementary open-drain transistors as motor coil drivers, automatic lock current shutdown, and recovery protections.

Additional, frequency generator (FG) output is for speed detection relatively.

To avoid coi
