Notes: 1. If VCC or VBATT is 0V, the other must be greater than 2.0V.
2. Battery charging-current is âââ. Battery discharge-current is â+â.
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 50kâ¦. WDI is biased to 0.3VCC.
