BQ35100: For bulk capacitor capacity decline detect

Part Number: BQ35100

Hi Team,

Is it OK to use BQ35100 ACC mode for bulk capacitor capacity decline detect?

If it is OK, ACC would accumulate the capacitor capacity value, right?

Can it sweep previous value as every read command?

Also, any calibration tool of BQ35100 need for factory test?

Thanks

Hi Daniel
The bq35100 is not for capacitors but rather for primary batteries. If you want to simply use the accumulator mode to coulomb count the charges out of the pack, you can. pls review the online materials such as the TRM, EVM user guide, and the training videos for the device to have a better understanding of how the gauge works
thanks
Onyx

Daniel,

To do the review more information is needed. Voltage of your capacitor/pack range and expected load current amplitude?

thanks,
