AH286

Hall-Effect Smart Fan Motor Controller

Features

General Description

- On chip Hall sensor

AH286 is a monolithic fan motor controller with Hall

sensor’s capability. It contains two complementary

open-drain transistors for motor’s coil driving,

automatic lock current shutdown, and recovery

protections. In addition, rotor-state detection (RD)

output is for Rotor-state detection.

- Rotor-locked shutdown

- Automatically restart

- Rotor-state detection (RD) output

- Built-in Zener protection for output driver

- Operating voltage: 3.8V~20 V

- Output current: I_O(AVE)= 500mA for SIP-5/SOT89-5

- Output current: I_O(AVE)= 400mA for SOT23-5

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

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

the rotor is blocked. Until the blocking is removed,

the motor recovers running normally.
