AH293

LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR

CONTROLLER

General Description

Features

AH293 is a monolithic fan motor controller with Hall sensor’s

capability. It contains two complementary open-collector

transistors for Motor’s coil driving, automatic lock current

shutdown, and recovery protections. Also, rotor-state detection

(RD) output is for speed detection.

On Chip Hall Sensor

Rotor-Locked Shutdown

Automatically Restart

Rotor-State Detection (RD) Output

Built-in Zener Protection for Output Driver

Operating Voltage: 1.8V~5.75 V

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.

•

Output Current: I_O(AVE)= 400 mA
