Hello Harish,

You can take a look at the TIDA-010247 reference design to see a stacked high-side FET implementation.

For low-side FETs, you can look at the Using Low-Side FETs with the BQ769x2 Battery Monitor Family application note. Stacking is similar between both devices, however the FET driving circuit would be the main difference.

HI Luis

Thanks for your feedback

So can I connect 12 cells of Bq76952 in lower AFE and remaining 12 cells of BQ76952 in upper AFE to achieve 24 Cells.

Also to achieve 12 cells configuration in each AFE do we need to short lower cells of AFE or upper cells of AFE.

Thanks
