Hi TI Team,
If Over Charge Capacity occurs, the OC bit or Over Charge fault condition can be cleared by a continuous amount of discharge over Over Charge Recovery. But how to reset the internal counter? Discharge the battery to Term Voltage reset it to 0? This is to prevent the OC from being set on the next charge, as we found that the OC was set again once the battery was charged up.
C.4.6.9 Over Charge Capacity (Offset 13)
The ba20z60-R1/bq20z65-R1 enters a overcharge fault and sets the [OC] flag in ChargingStatus if the internally counted remaining capacity exceeds FullChargeCapacity + Over Charge Capacity.
Thanks!
