Part Number:BQ78350-R1

Hello,

I observed two times an issue, BMS has both FETs off, what makes it unable to charge and discharge.

That happen when pack is discharged, then heats up above Overtemperature in Charge. Im not sure what is the sequention of flags (unfortunelly i dont have any logs now).

But the final state is:

Flag CUV = 1

Flag COT = 0

CHG fet and DSG fet off, and BMS is blocked.

Is that issue or I dont understand something?
