Abstract
A universal serial bus (USB) Type-C interface architecture includes a USB plug, a USB socket, a power delivery controller, a first pin, a second pin, a first resistor switch, a second resistance switch, a third resistance switch and a fourth resistance switch. The first pin includes a first end coupled to the USB plug, and a second end coupled to the power delivery controller. The second pin includes a first end coupled to the USB plug, and a second end coupled to the power delivery controller. The first resistance switch controls the connection between a first resistor and the first pin. The second resistor switch controls the connection between a second resistor and the first pin. The third resistor switch controls the connection between a third resistor and the second pin. The fourth resistor switch controls the connection between a fourth resistor and the second pin.
