Part Number: BQ76940 Dear Expert,
My customer faced BQ76940 VC15 voltage drop about 12mV when connect with NTC via TS3. hey used 13 series battery. What the reason caused this phenomenon?
Could you pls look into the case?
here am trying to make one circuit using TI BQ76940(as per datasheet connection) for communicate with arduino board.....i start it from scratch and also i have doubt about coding side also, how to boot this ic using arduino?...please share any reference…
Part Number: BQ76940 Hi..
BQ76940 AFE has Internal CC VREF for Current sense voltage reference but in the datasheet, not mentioned what is the actual CC VREF Value.
Part Number: BQ76940 Hi,
I want to do a thyrocervical calculation for ADC accuracy for comparison with the practical measurement of AFE Cell voltage, so I am not getting any Vref- "14 Bit ADC reference voltage for calculation" Please give me information…

Hello experts,
I am having a problem with the MOSFETs getting damaged when we do SCD. We have designed two boards as potential fixes for this problem. Board A has 4 N Channel FETs in parallel on each CHG and DSG side (MPN: BSC061N08NS5…
Part Number: BQ76940 hi
On page 11 of the BQ769X0 datasheet, for the 16-bit Coulomb Counter (CC) used in pack measurement with a range of ±200mV, the maximum Integral Nonlinearity (INL) is specified as ±40LSB. Does this imply that its (ENOB) is also 16…

I am using this IC for my BMS and found an uncertain behavior at -20 deg.C. When I am using my BMS at -20deg. C I see a jump in my NTC from -20deg. to -6degC when I change my supply voltage from 48V to 42V.
Hello Anish,
Glad to hear the initial issue was solved!
Can you describe exactly what you mean by "move to a different battery bank".
It is a bit difficult to understand the pictures sent.
What were the cell voltages before moving and after?…
