Hi Rotem,
1. 20mA is basically the maximum specified current from REGOUT, so the discussion was at maximum output current but ignoring any internal bq76940 current and FET current which would also affect REGSRC.
2. CAP1 should not be used for bq78350…
Hey Tom,
I'm having similar issues, but the above linked bqz file didn't fix my issues.
I am currently using bqStudio version 1.3.45, and I have updated the firmware on the BQ78350 to bq78350_R1_v1_03_build_22.srec. Please note that my part is from…
Other Parts Discussed in Thread: BQ76940 , BQ78350 , BQ76940EVM We're using a BQ78350 to manage a BQ76940 AFE in an e-bike application. We lose SMBus connectivity with the BQ78350 when the system is connected to the bike's electric motor under load. Communications…
I am also interested in getting hold of the bq78350 firmware file.
We are currently on a design around the bq78350-bq76940 chipset. We have a bq76940EVM at hand and we want to evaluate it.
Do you have a preliminary firmware file for evaluation purpose…
Hi Louis,
It is a bit difficult to describe since the schematic does not yet have reference designators.
The cell filter capacitors Cc are 1uF, you may want these smaller to avoid a voltage artifact during balancing.
You don't need the 100 ohm series…
Part Number: BQ76940 Other Parts Discussed in Thread: BQ78350-R1 , CSD19536KTT , I have fabricated a BMS using BQ76940 as AFE and BQ78350-R1 and Companion controller according the EVM's user guide. The system worked fine for a week for small discharge…
The bq76940EVM contains a blank bq78350. The function of the bq76940 may be evaulated as is, but the bq78350 must be programmed when its file is available before it will operate.
Yes, the bq78350 will retain settings through a power outage, once it…

Hi WM5295
We have the same problem with www.ti.com/.../bq76940evm and EV2400 .
When looking at www.ti.com/.../EV2400 > EV2400 Firmware Updater (ZIP, 8504 KB) > the release date is 19 Jan 2015 and it still doesn't work.
Do we need to wait longer…
Hi,
Thank you for your quick support. The yellow line ist pin SW of LM5007, but its AC-coupled, because PACK- is floating (because of the described failure) 10-20V over BAT-, which is connected to mass of my scope. It is just for showing, when LM5007…
