Pin Configuration
General Description
AH292 is a monolithic fan motor controller with Hall
sensor’s capability. It contains two complementary
open-collector transistors for motor’s coil driving,
automatic lock current shutdown, and recovery
protections. Besides, frequency generator (FG)
output is for speed detection relatively.
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. These protecting actions are
repeated and periodic during the blocked period.
Until the blocking is removed, the motor recovers
running normally.
