6.3.10 UVLO Protection

The VIN undervoltage lockout (UVLO) protection monitors the VIN pin voltage to protect the internal circuitry from low input voltage. When the VIN voltage is lower than the UVLO threshold voltage, the device shuts off and outputs are discharged to prevent misoperation of the device. The converter begins operation again when the input voltage exceeds the threshold by a hysteresis of 650mV (typical). This protection is a non-latch protection.
