Is there a white paper that clearly defines how to use MosFet turn on characteristics to suppress in-rush current?

Design is similar to the TLE9853 Eval board, H-bridge with larger Mosfet's.

With simulated inductive load we can control the current.

When testing an actual motor we experience an inductive in-rush current exceeding the pulse rating of the MosFet.

Hi @RLGeorge ,

You can use the soft-starting method with soft-starting hardware to reduce the inrush current.
