When a proper end-of-charge event is detected, the
device learns a new FullCAP register value based on
the RemCap
high, it is adjusted downward after the last valid end-
of-charge detection. If the old FullCAP was too low, it is
adjusted upward to match RemCap
the calculated state of charge from ever reporting a value
greater than 100%. See
The ICHGTerm register allows the device to detect when
a charge cycle of the cell has completed. The host
should set the ICHGTerm register value equal to the
exact charge termination current used in the application.

The device detects end of charge if all the following con-
ditions are met:
• SOC
• AND ICHGTerm x 0.125 < Current < ICHGTerm x 1.25
• AND ICHGTerm x 0.125 < AverageCurrent <
Values are stored in FV. Multiply the termination current
by the sense resistor to determine the desired register
value. This register has the same range and resolution
as the Current register.
