Note 2: The supply current drawn by the MAX691A/MAX800L/MAX800M from the battery excluding IOUT typically goes to 10µA when (VBATT - 1V) < VCC < VBATT. In most applications, this is a brief period as VCC 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 VOUT and GND. If unconnected, WDI is driven to 1.6V (typ), disabling the watchdog function. Note 7: The chip-enable resistance is tested with VCC = +4.75V for the MAX691A/MAX800L and VCC = +4.5V for the MAX693A/MAX800M. CE IN = CE OUT = VCC / 2. Note 8: The chip-enable propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
