PRODUCTION DATA.
The system must have a minimum VCC voltage to allow proper operation. This VCC voltage could come from either input adapter or battery, because a conduction path exists from the battery to VCC through the high-side NMOS body diode. When VCC is below the UVLO threshold, all circuits on the IC are disabled, and the gate-drive bias to ACFET and BATFET is disabled.
