Part Number: BQ76940EVM Other Parts Discussed in Thread: BQ76940 Hi;
I am working on Bq76940 referance design Tıda-00255 and I choose the sense resisitor 1m ohm as the same as on the EVM but there is a strange issue that I met.When the BATT- pin and GND…

Hi,
1) I would like to ask that what is the purpose of R58 (1k) and R59(1k) on BQ76940EVM.
I'm asking because, I have seen abnormal current on this line (Example: C10 to VC10X). Therefore, I see changes in cell voltages(Voltage unstability…
Hi,
If the connections match the EVM exactly, there should be no issues. I think the problem may be with the FETs, they are rated for a max current of 15A. I would choose a FET that can handle more current if you are going to discharge at 18A.

Part Number: BQ76940EVM Other Parts Discussed in Thread: BQ76940 , BQ76930 Hi;
I am working on bq76940 evm and the battery pack is 10S10P .Each cell group in parallel must be displayed from the interface.What would you recommend about that?
Thanks.
Part Number: BQ76940EVM Hello,
My application requires a continuous discharge current of 30A, which can be easily done by CSD19536KTT
I also noticed that the same FET is being used in TIDA 00792 .
Both have nearly the same Vgth and Rds of CSD19536KTT is comparatively…
