Notes:
1. If VCC or VBATT 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 VCC is within the operating voltage range.
WDI input impedance is 50 kΩ. WDI is biased to 0.3V
CC.
