Other Parts Discussed in Thread: BQ79616,
We seem to have a few instances where the lowest cell in a BQ79616 is reading low and causing cell imbalances. Sometimes it is the bottom BQ chip in the stack, sometimes not. I have gotten a hold of one board and the VC0 pin is sourcing current and the series R is dropping 30mV. I measured a few other boards and "R72" only drops about 0.4mV and is not sourcing. A replacement board fixed the issue in the pack. In this particular failed case it was the 3rd BQ in the stack. I believe the BQ79616-Q1 is damaged in some way. Has TI observed this issue with the VC0 pin sourcing current?
