Part Number:BQ20Z65-R1
I have a battery that was returned from our customer for a failure analysis that was in a permanent fail state. The PF Status bytes were 4000 and 0000. The GUI for the evaluation states that this is reserved bit, but the bq20z65-R1 tech reference states that the bit indicates the battery shutdown after another PF bit was set (PFVSHUT.)
First, which is the correct definition of that status bit.
Second, if the bit is a reserved bit, what does it mean if it is set. If it is PFVSHUT, what conditions could cause that bit to be set with no other PF bits set in either PF Status register?
