Dear team

The customer want to check the full charge conditions.

if set 4 hours (36k ohm). But the battery will be fully charged in two hours. How will the IC control charging in the next two hours?

    Hello Denny

    The BQ25171-Q1 will use a timer based charge routine, provide a fixed amount of current for the charge time.  Customer would want to set the charge current and time to match battery capacity.  For 4hr setting the charge current would be 4/C.
