There is no TUSB8020B in the schematic?

Hello,
From what I could see from the schematic picture(it is too blurry)"
Signal PWRCTL1 is not connected to the power switch.

Everything else looks correct.

Hi Elias,

PWRCTL1 is connected to the power switch at pin 4.
Is the Schematic ok?

PWRCTL1's series resistor is labeled as "NC".
The rest of the schematic looks correct.
