820-00840-A Part Identification

[MLS]

Hey all

Have an 820-00840-A with some liquid damage. There a rather large hole in the board which connects to a part thats not listed on any schematic I can find?

Looks to be PI3USB32224BXEAE , can't find pinouts so not sure where to run trace wire.

Pics attach and help appreciated!

Thanks mate

Found that part but not pinout or explanation of function. A bit more searching and https://www.diodes.com/assets/Datash...I3USB32212.pdf is the closest thing I've found so far with chip info, so USB 3.1 Mux/Demux (looks like more pins on short ends..).

As its a 2 Thunderbolt model I'm guessing that burned pin is a fair place to start.

Hoping someone can identify that pin connected to the burned pad so I can run a trace wire.

Mouser has the part listed (new from supplier) but no info. https://au.mouser.com/ProductDetail...PI3USB32224BXEAEX?qs=HXFqYaX1Q2xh6y8T79trwA==

Part is not on available schematics.

If anyone has the ability to name the broken/burned line in the above Pics so I can run a trace, that would be an amazing help
