(T AMB = 25 C, unless otherwise noted)
ELECTRICAL CHARACTERISTICS
V CC = +4.75V to +5.5V for the SP691A/800L , V CC = +4.5V to +5.5V for the SP693A/800M , V BATT = +2.8V, and T AMB = T MIN to T MAX unless otherwise
noted. Typical values apply at T AMB =+25 O C.
NOTE 1: Either V CC or V BATT can go to 0V, if the other is greater than 2.0V.
NOTE 2: The supply current drawn by the SP691A/693A/800L/800M from the battery (excluding I OUT ) typically
goes to 5 μ A when (V BATT - 1V) < V CC < V BATT . 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 SP691A/800L and V CC = +4.5V for the
SP693A/800M . 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 .
