Hello,

Where would the short you are trying to detect be located?

Thank you,

Zachary

It's not important where would be short.
We need to detect if high current trip in very short timing. It's similar with OCD when we have .
But the delay time 32us is not short enough for this feature.

Hi experts.

Could you check this again? Just wondering to confirm if there is no SCD protection in bq79731.

Hi,

Apologize for the delayed response. We don't have specific short detection pins. The only options would be to use the GPIO ADCs or the current sense pins for short detection.

Best,

Zachary
