Hi,
One possibility is that one of the VCx pins exceeded their differential abs max. This can occur from transients during the cell attachment process and is something we've seen happen several times. Our recommended solution for this is to place 8V Zener…

Hi there,
I'm designing a BMS using TI IC BQ76940 but I'm failing to understand how DSG and CHG pins works in that. I used reference deign given by TI and with this design…
Part Number: BQ76940 Other Parts Discussed in Thread: BQ78350 Tool/software: Hi Team We are developing the BQ76940 for a robot application and would like to have our schematic and PCB file reviewed before we put it up for production. We would like to…
Part Number: BQ76940 Tool/software: Dear TI expert,
According to the AFE datasheet, it is noted that factory calibration is performed at the TI side. Could you kindly clarify which specific parameters are calibrated during this process to ensure accurate…
Part Number: BQ76940 Other Parts Discussed in Thread: BQ76952 , Tool/software: Hi E2E,
When I trigger an OV condition, do I only need to write 1 to the OV bit in the SYS_STAT register to clear the OV status?
If yes, are there any other methods to clear…
Part Number: BQ76940 Other Parts Discussed in Thread: MSP430FR6989 Tool/software: Hi all,
I took BQ76940 IC for my BMS design for cell balancing and Monitoring. I took the MSP430FR6989 Launch Pad to Monitor the performance of the IC during i2c communication…
Part Number: BQ76940 Tool/software: Dear Expert,
We are utilizing the BQ76940 AFE to measure cell voltage data, accompanied by a companion IC that relays the data to our microcontroller. According to the datasheet, all AFE's GAIN and OFFSET values are…
Part Number: BQ76940 Tool/software: I am now using a resistor load discharge with an actual current of 10A, measuring a voltage of 6mV on the sample resistor with a value of 0.6mR on the sample resistor, but the value read in the CC register is 0x94FE…
