Part Number:BQ76930

Hi there:

we're under debug customer's schematic design for BQ76930 and CSD18542*3 in parallel for DSG path.

and found a ring voltage when the MOSFET turn-on & off

Please find the attached file and help us to find:

1. If we don't wanna change customer's layout design, is there any way (change Cap or else) to minimum this ring voltage?

2.Is there any reference document we can find to provide the solution for our customer modify design at next time.
