I currently use a TLE7181EM H bridge driver chip. My design is the same as the reference design Infineon published some years ago.
Now I would like the design to use SMT MOSFETs. Anything I need to look out for in selecting a MOSFET?
I see inventory of the ISC015N04NM5ATMA6. Would this part work?

Hello Gary
Thank you for posting on Infineon Forums.
If you are looking for an SMT MOSFET part, the safest way would be to pick the same part as in our evaluation board:
https://www.infineon.com/dgdl/appnote_7181_V1_2.pdf?fileId=db3a304336724dc40136779ef021476b
This is an IPD90N04S04-02.
I could not find that exact part but you can replace it with IPD90N04S04-05.
I could not find ISC015N04NM5ATMA6, but I could find ISC015N04NM5ATMA1 and it should work fine. In addition, it has a much lower Rdson than IPD90N04S04-05.
Please send us a link to the reference design you are referring to so that we can know your design requirements.
Best regards,
Pablo
