We have implemented the 77958 and the 77962 for the charging of a 2S battery configuration when connected to a general PD charger. The cells all charge from any level to 100% with no issues. However if we leave a standard PD charger connected after reaching 100% the batteries slowly drain. This drain is well in excess of self-discharge and only happens when a charger is connected. It seems as though we have a register set incorrectly as we would have expected that as the charge level drains that the charging circuit would have reasserted at a threshold of a few percent below 100%. But the PD interface does not restart. Our question is what would be the most likely registers to look at.
