Dear TI support team,

Is it possible to have multiple BQ79600 in a daisy chain architecture with BQ79631 and BQ7961X?

Thank you,

Hi,

I recommend you check out this previously answered question: https://e2e.ti.com/support/power-management-group/power-management---internal/f/power-management---internal-forum/1215634/bq79600-q1-communication-with-multiple-bq79600

Does this answer your question regarding the validity of multiple BQ79600 devices in a stack?

Thank you,

Pranav Ananthan

Hi Florent,

I apologize for that issue, but here is the answer posted in the above link that I was trying to share:

"You cannot use more than one BQ79600 in a stack. This will cause auto-addressing and read/write command errors because all the BQ79600 devices will have the same 00 address. This cannot be changed, and it will prevent the customer from being able to select which BQ79600 they want to read/write to."

Please let me know if this addresses and answers the question you had.

Thank you,

Pranav Ananthan
