AH291 Datasheet (Diodes Incorporated) - LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER

AH291, LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER

AH291 is a monolithic fan motor controller with Hall sensor’s capability.

It contains two complementary open-collector drivers for motor’s coil driving, automatic lock shutdown and restart function relatively.

Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocke
