AH286 - HALL-EFFECT SMART FAN MOTOR CONTROLLER

Datasheet Summary

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.

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.

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 driver when the rotor is blocked to avoid coil overheat.
