Part Number: BQ76930 Tool/software: Hi team,
Recently our customer feeded back there were some batteries stop charging / discharging because the malfunction of smapling cell voltages.
Our BMS use two bq76930 in serial to support 20S LFP cells management…
Part Number: BQ76930 Other Parts Discussed in Thread: BQ78350 , BQ76200 , Hi
Please help check the schematic, BQ76930+BQ78350 design with 7 series (MOS high-side control, using BQ76200 driver)
The cell voltage cannot be collected, and cannot communicate;…
Part Number: BQ76930 Hi,
I'm trying to select a suitable MOSFET to power the REGSRC pin. I don't understand the source follower topology proposed in the bq760x0 Family Top 10 Design Considerations section 9. Since the voltage at the drain (BAT) is…
Part Number: TIDA-00449 Other Parts Discussed in Thread: BQ76930 , , BQ76972 , BQ76952 Tool/software: Dear TI expert,
currently, i want to design one BMS for 25.6V20Ah battery module, i want to use MCU+BQ76930, but the two batteries (25.6V20AH) can…
Part Number: BQ76930 Hello:
The bq76930 chip is used on the 8s cell. The phenomenon is that the voltage of the seventh string is low after multiple cycles of charging and discharging of many modules
This is the current measured by the ammeter in…
Part Number: BQ76930 Hi Team,
During the use of BQ76930, if the external thermistor temperature measurement is initialized through I2C, it will cause the battery voltage sampling to jump. After shielding the temperature measurement, the voltage sampling…

Tool/software:
Dear Ti Team,
I would like to bring this critical issue to your attention, as it is highly important for us. We are currently receiving failure feedback from…
Part Number: BQ76930 Tool/software: Hi,
i'm changing the configuration from 10S to 7S.
With 10S there aren't problems, all cells are read and there is I2C comunication between uC and bq.
Reducing the number of cells and following the connection…
