AH281 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.
To avoid coil burning, rotor-lock shutdown detection
circuit shut down the output driver if the rotor is
blocked and then the automatic recovery circuit will
try to restart the motor. This function repeats while
rotor is blocked. Until the blocking is removed, the
motor recovers running normally.
