QFN 20 chip marking code

Hello, I have a chip in my hand and I cannot identify it. I have been trying for about a week. I would be glad if you can help me with this issue.

Hello lasertuw, welcome to the Forum community. I’m sorry, I wasn’t able to identify the part either. Hopefully, one of my colleagues will recognize it. Sorry I couldn’t help!

Thank you, I hope it is a material that can be found.
