Parameter Time Description
t

10 ns min Time between when V
DCIN
goes below 1.2 V and when FVDCIN is raised.
t

10 ns min Time between when V
DD
falls below 2.75 V and when battery switchover occurs.
t
3
30 ms typ
Time between when V
DCIN
falls below 1.2 V and when battery switchover occurs if V
DCIN
is enabled to cause
battery switchover.
t
4
130 ms typ
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
