AH286 HALL-EFFECT SMART FAN MOTOR CONTROLLER

AH286 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. Rotor-lock shutdown detection circuit turns off the output driver when .
