Note 2:
Either 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 internally serviced within the watchdog timeout period if WDI is left unconnected.
Note 5:
WDI input is designed to be driven by a three-stated output device. To float WDI, the “high-impedance mode” of the output
device must have a maximum leakage current of 10μA and a maximum output capacitance of 200pF. The output device
must also be able to source and sink at least 200μA when active.
Note 6:
The chip-enable resistance is tested with V
CC
= +4.75V for the MAX818L and V
CC
= +4.5V for the MAX818M.
