BQ77915: Issue regarding OCD delays

Part Number: BQ77915

Hello Everyone,

I have a question about the differences between OCD delays. Could someone please clarify this for me? I'm struggling to understand whether these delays are the same or if they differ, and what their applications might be.

Thank you very much!

  • Hi Shrey,

    Depending on the version of the bq77915, the OCD1 and OCD2 delay could be the same or different.

    If they are the same, then you can just treat the OCD with the larger threshold as if it does not exist as the OCD with the lower threshold will trigger at a lower current with the same timing.

    This FAQ (link) discusses why a device would have multiple OCD thresholds/delays. It's for a different device, but the ideas are the same.

    Regards,
