General Description
AH292 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, frequency generator (FG) output is for speed detection relatively.
To avoid coil burning, rotor-lock shutdown detection circu...
