Description

AH283 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, rotor-state detection (RD) output is for Rotor-state detection.

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 of AH283 repeats while the rotor is blocked. Until the blocking is removed,the motor recovers running normally.
