AH281

Hall-Effect Smart Fan Motor Controller

Features

General Description

- On chip Hall sensor

AH281 is a monolithic fan motor controller with Hall

sensor’s capability. It contains two complementary

open-collector drivers for motor’s coil driving,

automatic lock shutdown and restart function

relatively.

- Rotor-locked shutdown

- Automatically restart

- Built-in Zener protection for output driver

- Operating voltage: 10V~20 V, driver start up: 8V

(minimum)

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. This function repeats while

rotor is blocked. Until the blocking is removed, the

motor recovers running normally.

- Output current: I_O(AVE)= 300 mA

- Package: SIP-4L, SOT89-5L
