Note 1
:
Either V
CC
or V
BATT
can go to 0V, if the other is
greater than 2.0V.
Note 2
:
The supply current drawn by the SP791 from the
battery (excluding I
OUT
) typically goes to 10
μ
A when (V
- 1V) < V
CC
< V
. In most applications, this is a brief
period as V
CC
falls through this region.
Note 3
:
"+" = battery-discharging current,
"-" = battery-charging current.
Note 4
:
WDI is internally connected to a voltage divider
between V
and GND. If unconnected, WDI is driven to
1.6V (typ), disabling the watchdog function
.
