AH289
HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER
Features
* * * * * * * * * 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
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.
