hello ,

Based on the TI E2E forum discussion : https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1560974/bq78350-r1-shutdown-problem?tisearch=e2e-sitesearch&keymatch=Shutdown%20BQ78350-r1#

If I configure the CC Offset to 3, what impact will this have on the system's current measurement accuracy?

It will have a negligible impact as this number will be divided by Offset Samples and subtracted from the current.

It's not intended to be configured manually. The gauge has an auto-cal routine, which measures the offset error by internally shorting SRP-SRN when conditions allow. I recommend not touching this number.
