_______________________________________________________________________________________
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.
