AH289 High Voltage Hall-Effect Smart Fan Motor Controller

AH289 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain transistors for motor’s coil driving, automatic lock current shutdown, and recovery protections. In addition, rotor-state detection (RD) output is for Rotor-state detection. To avoid coil burning, rotor-lock shutdown detection circuit shut down .
