AH288 is a monolithic fan motor controller with Hall sensor’s
capability. It contains two complementary open-drain transistors
as motor coil drivers, automatic lock current shutdown, and
recovery protections. Additional, frequency generator (FG) output
is for speed detection relatively.
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.

Note: The optional Capacitor C1 and Diode D3 are for power stabilization. C1 is recommended to
be E-Cap., luF/25V; D3 is recommended to be Zener Diode, V Z =27V. Which C1and D3
value need to be fine tuned to optimize design for different coils and power suppliers .
