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. In addition a Frequency
generator (FG) output is also available for speed detection.
Rotor-lock shutdown detection circuit turns off the output driver
when the rotor is blocked to avoid coil overheat. Then, the
automatic recovery circuit will restart the motor. These protected
actions are repeated and periodic during the blocked period. Until
the blocking is removed, the motor recovers and runs normally.
