Customer is interested using the BQ7961x in their application and they want to know if this is the best device to meet their requirements, please see details below.
The way our pack is setup is in 4 segments of 18 series cells, using 2 daisy chained 12S balancing chips per segment each balancing 9 cells. We were looking at the BQ7961X series of chips to accomplish this; however, after reading through the documentation I did not see any methods to have multiple chips balancing the same segment (Ex. one chip balancing cells 1-9, one chip balancing cells 10-18).
Is this possible with the BQ7961X series of chips? or are there any other options from TI we could explore for balancing our pack?
