I have an experimental setup with which we are testing the bq40z50 for use in our product. Our system uses the PRES pin to wake the chip up and determine if a system is present, be that the charging source or the load.
If I wanted to replace the battery in the system, be that in the field or in the lab, e.g. if one of the cells died, what is the process that I need to follow to correctly replace the battery so that the chip doesn't become "confused" when the new battery is connected. Would I need to re-upload the "golden pack" parameters for the new battery, or do I just need to simply "reset" the chip.
On a side note: What does "resetting" the chip actually do? Does it reinitialise flash parameters to defaults or does it just update the RAM parameters?
