AH292 - ETC

AH292 Low Voltage Hall-Effect Smart Fan Motor Controller

AH292 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-collector transistors for motor’s coil driving, automatic lock current shutdown, and recovery protections. Besides, frequency generator (FG) output is for speed detection relatively. To avoid coil burning, rotor-lock shutdown detection circuit shut do.
