AH286 is a monolithic fan motor controller with Hall sensor’s

capability. It contains two complementary open-drain 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.

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.
