hi Danilo,
You can find our protection ICs on this page where you can select the parameters over-current in charge or in discharge.
BQ77905 and BQ77915 would work for the high-level requirements you raised, from 12C (1 IC as it goes from 3s to 5s) and they can be stacked for reaching higher voltages.

Here is an application note for a 20s application for instance.

Hi David,

Thank you for your quick response. The application of the over current protection is for DC Bus of 12VDC to 400VDC and I plan to suggest to the customer our eFuse but I can't find one that can operate at 400VDC. Is there a way we can configure the eFuse to work at 400VDC or do we have other solutions for over current protection?

Regards,

Danilo

Danilo,
Oh my bad. I thought you landed in my queue because you were asking for a solution for a battery. I do not have an answer to your question and do not know which team can help you on this.
