Part Number : AH286
Function : HALL-EFFECT SMART FAN MOTOR CONTROLLER
Package : SIP-5L Type, SOT89-5L Type
Manufacturers : Diodes Incorporated.
The AH286 is a single-chip solution for driving two-coilbrushless direct current (BLDC) fans and motors. The device includes a Hall-effect sensor, dynamic offset correction and two complementary open-drain output drivers with internal Zener diode protection.
To help protect the motor coils, the AH286 provides Rotor 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.
