Hi Furkan,
1. Yes, see the BQ76940EVM schematic or TIDA-00255
2. Yes, see TIDA-00449
3. Yes probably, you must design for the conditions. If needed, add drivers for the FETs
Hi Imran,
The bq76940 can be used for 12 cells. See the table in the data sheet section 8.1.1 for which cells to use. Connect the bq76940EVM using the schematic and terminal information in the user guide section 6.4. For simple evaluation you can just…
Hi Pritesh,
There is no programming language required. It is point and click with the BQStudio software. See the BQ76940EVM user guide for examples of the menus. The EVM does not have the BQ76200 on it but has the same BQ76940 and BQ78350-R1 which will…

Hi Rohit,
If you are using low side switching, see the BQ76940EVM user guide, or TIDA-00255 for an example.
If using high side see TIDA-00792. If you have a different high side driver or would prefer lower quiescent current during precharge you can…
