AH293 - Anachip

AH293 LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER

AH293 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, rotor-state detection (RD) output is for speed detection. To avoid coil burning, rotor-lock shutdown detection circuit shut down the ou.
