_______________________________________________________________________________________
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.
