I used the BQ25619 and set the following:
Charge Current: 900mA
Termination Current: 160mA
JEITA Cool I-SET: 20% ICHG
In the Cool range, the charge current is confirmed to be 180mA, as set.
However, the time it takes to fully charge is increased, and the battery is not fully charged even when the charge current is below 160mA. It seems to fully charge between 50 and 60mA.
I'd like to know how the termination current is set in the Cool range.
