AH286
HALL-EFFECT SMART FAN MOTOR CONTROLLER
Description
The AH286 is a single-chip solution for driving two-coil
brushless direct current (BLDC) fans and motors. The device
includes a Hall-effect sensor, dynamic offset correction and

Zener diode protection.
To help protect the motor coils, the AH286 provides Rotor
GND

286
Lock Protection which shuts down output drives if rotor lock is
detected. The device automatically re-starts when the rotor
lock is removed. A Rotor-lock Detect (RD) output flag allows
external monitoring of any motor locks.
The AH286 is available in SOT89-5L package.

Notes:
1. Typically it is recommended to us a 56 Ohm resistor for R1 and R2 and a 2.2 μ F E-Cap capacitor for C1, C2 and C3. These values
may need to be optimized depending on the coils used.
To help with IC protection it’s advised to add a Zener diode between Vdd and ground. The Zener diode should be chosen to help
prevent the supply voltage exceeding the maximum rating of the device.
