AH293 Datasheet (Diodes Incorporated) - LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER

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.

Also, rotor-state detection (RD) output is for speed detection.
