Abstract
A PD controller integrated circuit of a USB apparatus is disclosed, including a CC pad, a first switch, a second switch, a PD controller circuit, a high voltage sensing circuit, and a switch control circuit. The high voltage sensing circuit senses the CC pad. When a current voltage of the CC pad does not exceed a rated range, the first switch and the second switch connected in series between the CC pad and the PD controller circuit are turned on. When the current voltage exceeds the rated range, the first switch and the second switch are turned off, and the switch control circuit maintains a voltage of a common node between the first switch and the second switch at a reduced level lower than the current voltage.
