Hi Hardik,

We do not have a solution without stacking. We only have ICs supporting up to 16S. For low-side switching, you could reference TIDA-01093 (https://www.ti.com/tool/TIDA-01093 ), but use the BQ76940 instead of the BQ76930. Or in this case, you could use one BQ76940 and one BQ76930 for 22 cells.

Best regards,

Matt
