Technology - Hall Effect Fan Motor Controller - Guidance [Weikewei]

The AH283 series is a single pieceFan motor controllerIt contains two complementary open collector transistors as motor coils insideDriverThe automatic locking current shutdown and automatic recovery circuit, as well as the rotor state detection RD output for rotation state detection. In order to prevent coil burnout, if the rotor lock detection circuit in AH283 detects that the rotor is locked, it will turn off the output driver, and then the automatic recovery circuit will repeatedly attempt to restart the motor rotor during the rotor lock period until the rotor lock is eliminated, and the automatic recovery circuit will restartMotorUntil normal rotation is restored.

Main features:

● Built in output driver clamp protection

● The rotor is locked and turned off

● Automatic restart

● Rotation state detection (RD) output

Power supply voltage 10~20V (minimum 8V for driver startup)

Maximum output current louT (AVE)=300mA
