Hello Andreas7
Good Day!
Thank you for contacting us.
There is an evaluation board available for the NAFEB43388, which was recently released. Please note that this release has not been made to the general mass market yet. It is currently in CQS (Customer Qualification Samples) status, which means it has been released only to selected customers. As a result, schematics and other related documentation have not been published at this time.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
