PART OBSOLETE - NO ALTERNATE PART AH287 HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Features General Description On Chip Hall Sensor AH287 is a monolithic fan motor controller with Hall sensors capability. It contains two complementary open-drain drivers for Rotor-Locked Shutdown motors coil driving, automatic lock shutdown and restart function Automatically Restart relatively. Built-in Zener Protection for Output Driver Operating Voltage: 3.8V~28V Rotor-lock shutdown detection circuit turns off the output driver Output Current: I = 400mA O(AVE) when the rotor is blocked to avoid coil overheat. Then, the Lead Free Packages: SIP-4L and SOT89-5L (Note 1) automatic recovery circuit will restart the motor. These protected SIP-4L and SOT89-5L: Available in Green Molding actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally. Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (Note 2) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative.
