On Chip Hall Sensor
Rotor-Locked Shutdown
Automatically Restart
Rotor-State Detection (RD) Output
Built-in Zener Protection for Output Driver
Operating Voltage: 3.8V~28V
Output Current: IO (AVE) = 400mA
Lead Free Finish/RoHS Compliant for Lead Free
products (Note 1)
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.
