Overview
AH286 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~20 V Output current: IO(AVE) = 500mA for SOT89-5L Lead Free Packages: SIP-5L and SOT89-5L General Description AH286 is a monolithic fan motor controller with Hall sensor’s capability.
It contains two complementary open-drain transistors for motor’s coil driving, automatic lock current shutdown, and recovery protections.
In addition, rotor-state detection (RD) output is for Rotor-state detection.
Rotor-lock shutdown detection circuit turns off the output driv...
