AH287
HIGH VOLTAGE HALL-EFFECT SMART MOTOR CONTROLLER
chip Hall sensor Rotor-locked shutdown Automatically restart Built-in Zener protection output driver Operating voltage: 3.8V~28V Output current: IO(AVE) 400mA Lead Free Packages: SIP-4L SOT89-5L (Note SIP-4L: Available "Green" Molding Compound Lead Free Finish/RoHS Compliant (Note
General Description
AH287 monolithic motor controller with Hall sensor's capability. contains complementary open-drain drivers motor's coil driving, automatic lock shutdown restart function relatively. Rotor-lock shutdown detection circuit turns output driver when rotor blocked avoid coil overheat. Then, automatic recovery circuit will restart motor. These protected actions repeated periodic during blocked period. Until blocking removed, motor recovers runs normally.
Typical Application Circuit
