PRODUCTION DATA
To extend battery life and minimize power when the system is powered off during system idle, shipping, or storage, the device turns off BATFET so that the system voltage is floating to minimize the battery leakage current. When the host sets the BATFET_DIS bit, the charger can turn off the BATFET immediately or delay by tBATFET_DLY as configured by the BATFET_DLY bit. To set the device into ship mode with the adapter present, the host has to first set BATFET_RST_VBUS to 1 and then BATFET_DIS to 1. The charger will turn off the BATFET (no charging, no supplement) while the adapter is still attached. When the adapter is removed, the charger will enter ship mode.
