In a scenario where the device is enabled and V_OUT is greater than V_IN, there is potential for reverse current to flow through the pass FET or the body diode. When the reverse current threshold is exceeded (about 900 mA), there is a delay time (t_RCB) before the switch turns off to stop the current flow. The switch remains off and block reverse current as long as the reverse voltage condition exists. After V_OUT has dropped below the release voltage threshold (V_RCB) the device turns back on. When the ON pin is pulled low, the device constantly blocks reverse current.
