AH285 - Hall-Effect Smart Fan Motor Controller

Datasheet Summary

Description

AH285 is a monolithic fan motor controller with Hall sensor’s capability.

It contains two complementary open-drain transistors as motor coil drivers, automatic lock current shutdown, and recovery protections.

Additional, frequency generator (FG) output is for speed detection relatively.

Features

  • s - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Frequency generator (FG) output - Buil t-in Zener protection for output driver - Operating voltage: 3.8V~20V - Output current: IO(AVE) = 500mA for SIP-5/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-5L, SOT23-5L, SOT89-5L.
  • General.
