AH286
HALL-EFFECT SMART FAN MOTOR CONTROLLER
General Description
Features
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.

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~20 V
Output current: IO(AVE) = 500mA for SOT89-5L
Lead Free Packages: SIP-5L and SOT89-5L
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.
