Description
Time between when V DCIN goes below 1.2 V and when FVDCIN is raised.
Time between when V DD falls below 2.75 V and when battery switchover occurs.
Time between when V DCIN falls below 1.2 V and when battery switchover occurs if V DCIN is enabled to cause
battery switchover.
Time between when power supply restore conditions are met (V DCIN > 1.2 V and V DD > 2.75 V if BATPRG[1:0] =
0b01 or V DD > 2.75 V if BATPRG[1:0] = 0b00) and when V SWOUT switches to V DD .
