Hi,

Why BQ771807DPJR IC required in BQ76952EVM 16S BMS. Weather BQ76952 AFE will not handle Over voltage protection????

Hi Pradeep,

The BQ771807 is there to demonstrate that the parts work together. In some cases, laws in the U.S. require a secondary protector on batteries. The BQ76952 can handle over voltage protection.

Hi Pradeep,

For reduced cell counts, please refer to timestamp 7:30 in this video: Creating the Schematic for BQ769x2 Battery Monitors - YouTube. Additionally, you may find the BQ76952 product folder very helpful for future questions. I will link it here: BQ76952 data sheet, product information and support | TI.com. I hope this helps!
