Note 1: Either V CC or VBATT can go to 0V, if the other is greater than 2.0V.
Note 2: The supply current drawn by the MAX691A/MAX800L/MAX800M from the battery excluding I OUT typically goes to 10μA
when (VBATT - 1V) < V CC < VBATT. In most applications, this is a brief period as V CC falls through this region.
Note 3: “+” = battery-discharging current, “--” = battery-charging current.
Note 4: Although presented as typical values, the number of clock cycles for the reset and watchdog timeout periods are fixed and
do not vary with process or temperature.
Note 5: RESET is an open-drain output and sinks current only.
Note 6: WDI is internally connected to a voltage divider between V OUT and GND. If unconnected, WDI is driven to 1.6V (typ),
disabling the watchdog function.
Note 7: The chip-enable resistance is tested with V CC = +4.75V for the MAX691A/MAX800L and V CC = +4.5V for the
MAX693A/MAX800M. CE IN = CE OUT = V CC /2.
Note 8: The chip-enable propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
