Note 2:
Either V
or V
can go to 0V, if the other is greater than 2.0V.
Note 3:
"-" = battery-charging current, "+" = battery-discharging current.
Note 4:
WDI is guaranteed to be in an intermediate, non-logic level state if WDI is floating and V
CC
is in the operating voltage range.
WDI is internally biased to 35% of V
CC
with an input impedance of 50k
