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