CCS/BQ40Z60: Unexplained power downs that may be related to BTP operations

Part Number: BQ40Z60

Tool/software: Code Composer Studio

Hi,

We are getting intermittent power downs where the BQ appears to shut off the DSG FET for no apparent reason. We are logging at the time and see that the BTP_INT bit is either set in these cases or has been recently cleared (in the last 2-20 minutes). We have BTP_EN = 0, so we should not get any unnecessary BTP behavior.

This is in fielded equipment, and we have not been able to replicate in the lab. So we don't have much to go on.

Any ideas on what this might tell us?

Thanks,
