Hello,
My customer wants to measure cell voltages in the range of -1.2V to +3.5V. I assume there might be limitations in using the S-ADC in this case.
In particular, they are very interested in understanding how the open wire detection function operates. Since they are unable to use the S-ADC, they are considering detecting open wires based on the measured cell voltages in the main controller.
Question 1:
If an open wire condition occurs, what voltage will be observed between the affected cell terminals?
Question 2:
For the unused S-ADC pins, is it acceptable to leave them open?
Thank you for your support.
