HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR

CONTROLLER

General Description

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~28V

Output Current: I_{O (AVE)}= 400mA

Lead Free Finish/RoHS Compliant for Lead Free

products (Note 1)

AH289 is a monolithic fan motor controller with Hall sensor’s

capability. It contains two complementary open-drain transistors

for motors coil driving, an automatic lock current shutdown, and

recovery protection. In addition, the 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. Then, the

automatic recovery circuit will restart the motor. These protected

actions are repeated and periodic during the blocked period. Until

the blocking is removed, the motor recovers and runs normally.
