Abstract
A Universal Serial Bus (USB) device includes a USB Type-C connector having a configuration channel (CC) terminal and an integrated circuit (IC) controller. The IC controller comprises a VCONN pin coupled to the CC terminal of the USB Type-C connector, an output terminal, and an on-chip voltage protection circuit coupled between the VCONN pin and the output terminal. The on-chip voltage protection circuit comprises a switch coupled between the VCONN pin and the output terminal, a pump logic coupled to a gate of the switch, a resistor coupled between the VCONN pin and the gate of the switch, and a diode clamp coupled between the gate of the switch and ground.
