Anyone knows what IC this is?

Hey there,

After the USBC Port replacement my Steam Deck still did not charge. I double checked each line from the port to be sure everything is good there now. It had troubles recognizing one of two usb orientations and failed to make the PD handshake. After I checked everything and removed this IC, as I suspected it to be faulty everything startet up again.

Now I can not identify this IC to replace it. It has most likely a marking on it „3m“ and above there is something like an 8. Here are some Photos of the IC that I made. I think it’s size is something about 0,8-0,9mm.

One of the four pads is connected to ground. I think after the Port damage this IC was burnt and shorted to ground, so that’s why it started working now again.

Does anyone know for sure what the replacement part for this is? Thanks!
