Anachip AH282A-PLA Hall-effect smart fan motor controller Datasheet

AH282
Hall-Effect Smart Fan Motor Controller
„ Features
„ General Description
- On chip Hall sensor
- Rotor-locked shutdown
- Automatically restart
- Frequency generator (FG) output
- Buil t-in Zener protection for output driver
- Operating voltage: 10V~20V, driver start up: 8V
(minimum)
- Output current: IO( AVE ) = 300 mA
AH282 is a monolithic fan motor controller with Hall
sensor’s capability. It contains two complementary
open-collector transistors as motor coil drivers,
automatic lock current shutdown, and recovery
protections. Additional, 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. This function repeats while
the rotor is blocked. Until the blocking is removed,
the motor recovers running normally.
