Hi,

Thanks for the post!

The MOSFET used in 6EDL7141 Evaluation board is rated for 40V only even though maximum operating voltage of 6EDL7141 Gate driver IC is 60V.

Considering voltage overshoot due to parasitic components and safety margin for the MOSFET, maximum operating voltage of the Evaluation board is set to 24V.

We can increase operating voltage of the board by changing the MOSFET but we need to keep above factors in mind while design.

Hope this will clarify your doubt. Kindly feel free to post your queries.

Thank you!
