Abstract
A USB Type-C interface chip having a CC pin. In an embodiment, the chip includes an internal unit coupled through a signal path to the CC pin; a high voltage detection unit coupled in the signal path, for detecting a voltage at the CC pin and comparing the detected voltage and a reference voltage; a high voltage protection unit for protecting, in response to the comparison result of the high voltage detection unit the internal unit from high voltage possibly present at the port of the chip.
