ELECTRICAL CHARACTERISTICS (continued)
(V

= 4.75V to 5.5V, VBATT = 2.8V, T
A
= T
MIN
to T
MAX
, unless otherwise noted.)
Note 1:
Either V
CC
or VBATT can go to 0V, if the other is greater than 2.0V.
Note 2:
The supply current drawn by the MAX791 from the battery (excluding I
OUT
) typically goes to 10μA when
(VBATT - 1V) < V
CC
< VBATT. 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
OUT
and GND. If unconnected, WDI is driven to 1.6V (typ),
disabling the watchdog function.
Note 5:
CC
= 4.75V V
–—IN
= V
C—OUT
= V
CC
/ 2.
