Features
AH289
HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR
CONTROLLER
General Description
• 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)
• Lead Free Packages: SIP-5L and SOT89-5L
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.
