hi ti engineer:
8.3.1 Power-Up from Battery Without DC Source
If only battery is present and the voltage is above VVBAT_UVLOZ, the BATFET turns on and connects battery to
system.
------..>>>>>> if without dc adapter , and only battery insert,
Does the system power from battery until battery depleted? that is to say,in this mode ,the bq25708 cannot turn off the BATFET until battery depleted?
