Notes:
1. If V
CC
or V
BATT
is 0V, the other must be greater than 2.0V.
2. Battery charging-current is “-”. Battery discharge current is “+”.
3. WDI is guaranteed to be in an intermediate level state if WDI is floating and V
CC
is within the operating voltage range.
WDI input impedance is 50 kΩ. WDI is biased to 0.3V
CC
.
