... If the load resistor is removed, the V - pin voltage will be pulled down to the V SS level. Thereafter, the IC will be released from the over-current/short-circuit detection state when the V - pin voltage becomes equal to or less than the over-current detection voltage, and the Dout pin returns to “H” after over-current release delay time set by the internal counter.

... Short-circuit detection can be made independently. Excessive charger detection cannot be made during over-discharge, over-current and short-circuit detection. And its delay time starts after the Dout pin returns to “H”. LV51133T Operation in case of detection overlap Over-charge detection is preferred. If over- discharge state continues even after over- charge detection, over-discharge detection is resumed ...
