General Description

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.
