AH292

Low Voltage Hall-Effect Smart Fan Motor Controller

Features

General Description

- On chip Hall sensor

AH292 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. Besides, frequency generator (FG)

output is for speed detection relatively.

- Rotor-locked shutdown

- Automatically restart

- Frequency generator (FG) output

- Built-in Zener protection for output driver

- Operating voltage: 1.8V~5.75 V

- Output current: I_O(AVE)= 400 mA

To avoid coil burning, rotor-lock shutdown detection

circuit shut down the output driver if the rotor is

blocked and then the automatic recovery circuit will

try to restart the motor. These protecting actions are

repeated and periodic during the blocked period.

Until the blocking is removed, the motor recovers

running normally.

- Package: SIP-5L, SOT23-5L, SOT89-5L
