8.3.6 Powering the System When Battery is Discharged

There are two methods for powering the system under a dead battery condition. Case 1: The EN pin can be tied to ground so that the nFET is always ON (when VUVLO < VBUS_CON < VOVP) and an external charger can power VBUS. Case 2: If EN is controlled by a Power Management Unit (PMIC) or other logic, VBUS_POWER can be used to power the PMIC. In Case 2, once the device is enabled, tDELAY + tSS, work together to meet the USB Inrush Current compliance.
