FEATURES
- On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Frequency generator (FG) output - Buil t-in Zener protection for output driver - Operating voltage: 3.8V~20V - Output current: IO(AVE) = 500mA for SIP-5/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-5L, SOT23-5L, SOT89-5L GENERAL DESCRIPTION
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.
