Nintendo Switch Joy-Con - Not Working

[an231]

Hello,

 

I have a Joy-Con that doesn't work. A chip is missing as shown. Can anyone identify? Or indicate an equivalent component? I had to look at the other Joy-Con and I think I identified it but I can't find it.
A friend also send a picture of is Joy-Con.

I appreciate the help.
