General Description
AH289 is a monolithic fan motor controller with Hall sensor’s
capability. It contains two complementary open-drain transistors
for motors coil driving, an automatic lock current shutdown, and
recovery protection. In addition, the 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.
