Part Number: BQ76922 Tool/software: Hello,
Are there any max slew rate requirements for any of the input pins going to the DFE? Since we can have noisy signals, we just want to make sure we are not violating any pin ratings:
Thank you, Keith
Part Number: BQ76922 Tool/software: Hello
I am designing a system around BQ76922RSNR, for safety analysis I was able to find FIT rates but I couldn't find any pin level FMEA sheet which states FIT rates of individual pins.
Please provide pin level…

Hello team,
We are testing a short circuit protection based on BQ76922.
Battery pack: LiFePO4 4S 20Ah.
We do tests with different cables and observed one issue with a cable with high parasitic inductance (1.4m 10AWG…
Dear Alexis,
my design is for drone so i dont want any unintentional shutdown or power loose while operating. The circuit at TS2 pin is for not entering shutdown, we tried it on demoboard. At demoboard, We observed a full shutdown even if we keep this…
Hi Vladislav,
It should depend on your cell capacity and how long you want to balance the battery cell.
For example, if you want to balance 5% SOC of 25Ah cell in 10 hr. You need 25*5%/10=125mA.
BQ76922 can support 100mA max internal balancing current…
Part Number: BQ76922 Tool/software: I built a board based on the EVM schematic. I simulate cells with 200ohm resistors. I supplied 15V to PACK pins, enabled CHG and DSG FETs and this is what the chip reads.
The cell voltages are correct, but PACK and…
