Hi Ray,
I suggest taking a look at this 20s TI Reference Design: https://www.ti.com/tool/TIDA-01093
Many users use the BQ76940 (2 x 15s) in place of the BQ76930 (2 x 10s) used in this design for applications up to 30 series cells.
Best regards,…

Hi Kaile,
Thank you for sharing the image. Can you measure the cell voltages with a multimeter and compare them to the voltages measured by the BQ76930? Let me know what you observe for each of the 20 cells (measured vs. reported by BQ76930). Also,…
Part Number: BQ76940 Other Parts Discussed in Thread: TIDA-01093 , Hi,
My customer is using two 76940 at the same time. I want to confirm how to prevent the conflict of the I2C to make two 76940 can be read at the same time?
They are designing base…
Hello David,
Welcome! Yes, this is possible.
We have a reference design for the BQ76930, TIDA-01093 , which is from the same family as the BQ76940 (the BQ769x0 family).
You could stack two BQ76940 in the same way.
Regarding Low-Side vs. High-Side…
