FEATURES
- On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Rotor-state detection (RD) output - Buil t-in Zener protection for output driver - Operating voltage: 1.8V~5.75 V - Output current: IO( AVE ) = 400 mA - Package: SIP-5L, SOT23-5L, SOT89-5L GENERAL DESCRIPTION
Besides, rotor-state detection (RD) output is for speed detection. 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. Until the blocking is removed, the motor recovers running normally.
