Other Parts Discussed in Thread: BQ3050 Hi All ,
My code will read voltage/current/temperature/capacity/black date within 1 second. After read the data, I will write the seal command to gas gauge. After 2 seconds delay, the code will loop in.
I continuously…
Other Parts Discussed in Thread: BQ3050 I have a 4S1P pack with 3400mAh 18650 batteries. I am trying to test the cell balancing feature. I noticed that most of the reference designs have a 100 Ohm resistor into the Vx pins of the BQ3050. If I have a 4V…

Other Parts Discussed in Thread: BQ3050 Hi,
My Name is David and I need to ask a TI engineer a question off of the public forum. It is in regards to our battery management system that uses a BQ3050 and it's non-linear RSOC performance below 20%.
Please…
We have a 4S1P configuration. When we are installing the cells, the chip gets latched in a CUV state and turns off the discharge FET. These are all new cells charged to 4.2V. One way to clear this fault is to provide a positive charge current. Our problem…
The solution was adding 10K pullups to the SMBus signals. There were no other problems with the SMBUs, but downloading the .senc file would not work without pullups.
Thanks Tom - I was able to load your SENC file using the tool for the bq3050 and was able to export the DFI file using the tool for the bq20z95. However, I was unable to load and write the DFI using the bq20z95 tool, so it appears that I won't be able…
Other Parts Discussed in Thread: BQ3050 I have a 4s1p setup using Panasonic's 3400mAH NCR18650B. Has anyone used these before with a BQ3050 that can provide the CEDV coefficients?
