Macbook A1708 / 820-00840-A / Can't find IC on schematic neither boardview

[GfilipeZ]

Hi,

I'm diagnosing a machine that won't turn on.
When I did the visual inspection under the microscope, I detected a blown IC next to the USB-C connectors.
But i can't find this IC on schematic neither boardview.

I send attached pictures of the IC and its location.

Does anyone know if there is another version of Logic Board, which has this IC on schematic and boardview?

Best regards.

820-00840 ❌ ✅ Use 820-00875 which does not have the PI3USB32224BXEAE near USB-C ports and different populated parts for SSD_BOOT_L/SSD_PWR_EN_L (see A1708 SSD). Correct boardview is available in XinZhiZao.

The part is from Pericom (Diodes Inc.) (p/n PI3USB32224BXEAE):

I am having just now exactly the same problem: the PCB says 820-00840-A, but the boarview file does not show the above mentioned IC. And it's fried.
Thanks a lot for your help. I really appreciate it.
