Abstract
A chip is provided. A power transmission path and a data transmission path are coupled between an upstream port and a downstream port. A first detection unit generates a first trigger signal when a voltage level of the power transmission path reaches a first predetermined value. A first control unit turns on the data transmission path according to the first trigger signal. A second detection unit detects a voltage level of the data transmission path. When the voltage level of the data transmission path matches a pre-determined condition, the second detection unit generates a second trigger signal, and the first control unit turns off the data transmission path according to the second trigger signal. A setting unit sets the voltage level of the data transmission path when the first control unit turns off the data transmission path.
