Patent abstract

USB interface and charging port controller integrated circuits and systems are presented for interfacing USB power and data signaling with a host circuit, in which an ESD protection diode is integrated in the IC, having an anode connected to a data terminal of the IC and a cathode connected to the positive USB bus voltage terminal for directing ESD transient current from the data terminal to the USB bus voltage terminal for dissipation to an external bus capacitance connected between the USB bus voltage terminal and a USB ground node on a host system circuit board.
