Agent - Hall Motor Controller - Service [Weikewei]

AH284 is a single-chip fan motorcontrollerIt contains two complementary open drain outputs as drivers for the motor coil, which are interrelated with automatic lock off and automatic resetStart circuit. In order to prevent the burning of the coil, if the rotor lock detection circuit in AH284 detects that the rotor is locked, it will turn off the output driver, and the automatic restart circuit will repeatedly attempt to restart the motor rotor during the rotor lock period until the rotor lock is eliminated, and then 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 "

● Power supply voltage 3.8~20V

● Output current l_OUT(AVE) =500mA (SIP -4，S0T89 -5)

I_OUT(AVE) =400mA (SOT23 -5)
