Note 1:
The setting in the DAC is guaranteed to remain valid as long as V
DD
is greater than the UVLO threshold.
Note 2:
BATT Operating Range is guaranteed by the Microsecond-Volt Time Constant specification.
Note 3:
Current sourced from a pin is denoted as positive current. Current sunk into a pin is denoted as negative current.
Note 4:
Guaranteed by design.
