I'm trying to pick a fuel gauge to replace my BQ24725. I need a part that is more flexible than this part that has a fixed CHEM_ID. I ran the Chem ID selection tool and found the BQ24725 has a 6% error. Other chemistry choices can get me under 2%.
It seems that the BQ27520-G4 is a good replacement. Anyone have comments on that choice or that chip in general?
