[SOLVED] Help to identify component

[Erwin Ried]

Hello, I was testing some boards on my msi laptop and I made some magic smoke appear from one of the usb 3 ports. With the smell and everything. The port is dead now. I can see a crack in a 8 pin chip that is near the dead port

can anyone tell me if this is an standard part for (I think manages usb3 power) similar boards? Can I exchange it for one from a usb 3 cheap hub?

Thanks!

next to USB inputs, My guess maybe TVS Diodes?

Nice keyword so... Do I check which pin correspond to the usb port and replace it for a similar diode based on the Pinout? I am guessing there is 8 pins for 4 pairs of vcc d+ d- gnd

Likely a distribution switch. See datasheet

When you reinstall it, be sure to plug the FFC cable all the way into the connector! I just blew up my GS63VR's audio codec chip by not fully insert the audio/USB FFC, and a chip replacement won't help. I guess I also blew up some audio related circuitry in PCH since Windows can't detect audio device at all now.

Can you sell me your broken board? This is the same pc

Likely a distribution switch. See datasheet

Mmm I have to check the position of gnd, sounds feasible too

Just to close the case, I fixed it with a similar chip.

Likely a distribution switch. See datasheet

You are correct, it was that. I found a TPS2069 http://www.ti.com/product/TPS2069 in a broken lenovo pc and the pinout matched, so I replaced it and my laptop is fully operational again

Thanks for the hints, they were really helpful

Congrats!, now that is what I call innovative approach.

And you are very kind to the donor board, so many kapton tapes applied for the extraction of 1 IC.
Is that a pin to pin compatible, how come the jumper wires are not visible?

[Erwin Ried]

Thanks. Yeah, I might need more pieces from that donor board

Which jumper wires? From my drawing? they are connected inside the chip (to handle more current?... I guess)
