TIDA-00449: BQ76930 BMS IC

Isn't the low pass filter with 1k ohm and 0.22uF connected to the rc and cc integrated input, I didn't see a different place connected to the c5 point, so I asked?

I'm sorry, I didn't understand your question. The C5 shown in the figure below is the device required for battery sampling input filtering. Thanks

I'm sorry, I couldn't explain myself clearly, I actually asked this, I couldn't find a different place where c5 was connected in the circuit as c5, that's why I asked.

The c1 connected from the 1st cell also serves to start the ts1 pin and the integrated connected to the button, but I could not understand where c5 is connected. I will not use an additional voltage, current circuit in my system, I think I will read these values from the integration as in the reference design, I wonder if this part was used for this reason.

I'm sorry, I think your description of the problem is not clear, I can't clearly understand what you want to ask. Cell 10 is connected to VC10 through R1, C1, and Cell 10 is connected to BAT through D6 to start the internal LDO to provide TS1 with a pull-up for temperature sampling.

For C5, it is just a differential input, the same as C1/C2/C8/C9.... Cell 8 is connected to VC8 through R11, C5. Then there is no other connection...

Thanks
