... 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. Over-charger detection does not work during over-discharge, over-current or short-circuit detection and the delay time starts after return from these states. LV51137T 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 ...
