ELECTRICAL CHARACTERISTICS (continued)
(V CC = 4.6V to 5.5V for the MAX80_L, V CC = 4.5V to 5.5V for the MAX80_N, V CC = 4.35V to 5.5V for the MAX80_M; V BATT = 2.8V;
T A = T MIN to T MAX . Typical values are at V CC = 5V and T A = +25°C, unless otherwise noted.)

Note 1: Either V CC or V BATT can go to 0V if the other is greater than 2V.
Note 2: The supply current drawn by the MAX80_ 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 typically driven to 1.8V,
disabling the watchdog function.
Note 5: The chip-enable resistance is tested with V CE IN = V CC / 2 and I CE IN = 1mA.
Note 6: The chip-enable propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
Note 7: If CE IN goes high, CE OUT goes high immediately and stays high until reset is deasserted and CE IN is low.
