Part Number: BQ2961 I'm using the BQ2961 with 2 Li-Ion cells. Figure 25 in the (SLUSBU5D –NOVEMBER 2013–REVISED JANUARY 2017) datasheet shows a 3 cell example for a bq2961 where V4 is connected to V3. Is this the correct thing to do?
So in my case where…

Part Number: BQ40Z50 Other Parts Discussed in Thread: BQ2961 Dear TI Technical Expert，
Currently i am using BQ40Z50 and BQ2961 design one BMS, when the second overvoltage protection, the BQ2961 OUT pin output voltage is 7V and BQ40Z50 FUSE pin output…
Hi wyatt,
I have taken your inputs that as been very useful to our research, One final doubt BQ2961 over voltage controller ic can control single cell(1s) and i have using USB connection instant of junction terminals what is you through.

Hi Nils,
Regarding the BQ2961, the OVP and UVP are factory programmed and cannot be changed. There are different options available - see the Device Options Table 1 in the datasheet.
I will leave the remaining questions for the BQ40Z50 for the gauge…
Hi David,
I suppose if you are attaching the cells individually, this may work. I am concerned about what would happen if one device was in fault mode and the other was not.
Have you looked into some of our 2S protectors? These may be a better fit…
Hi Subrata,
Please refer to the datasheet for the typical application. If you would like an EVM the bq40z50 has the bq2961 device on board.
Thanks
Miguel
