FEATURES
- On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Built-in Zener protection for output driver - Operating voltage: 3.8V~28V - Output current: IO(AVE) = 400mA - Package: SIP-4L, SOT89-5L GENERAL DESCRIPTION
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 rotor is blocked. Until the blocking is removed, the motor recovers running normally.
