ELECTRICAL CHARACTERISTICS (continued)
(V CC = 4.60V to 5.5V for the MAX807L, V CC = 4.50V to 5.5V for the MAX807N, V CC = 4.35V to 5.5V for the MAX807M,
V BATT = 2.8V, V PFI = 0V, T A = T MIN to T MAX . Typical values are tested with V CC = 5V and T A = +25°C, unless otherwise noted.)

Note 1: Either V CC or V BATT can go to 0 if the other is greater than 2.0V.
Note 2: The supply current drawn by the MAX807 from the battery (excluding I OUT ) typically goes to 15μA when (V BATT - 0.1V)
< V CC < V BATT . In most applications, this is a brief period as V CC falls through this region (see Typical Operating Characteristics ).
Note 3: “+”= battery discharging current, “-”= battery charging current.
Note 4: WDI is internally connected to a voltage-divider between V CC and GND. If unconnected, WDI is driven to 1.8V (typical),
disabling the watchdog function.
Note 5: Overdrive (V OD ) is measured from center of hysteresis band.
Note 6: The chip-enable resistance is tested with V CE IN = V CC /2, and I CE IN = 1mA.
Note 7: The chip-enable propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
