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.

USB controller ESD protection apparatus and method

A circuit includes a comparator to generate a clamp output signal by monitoring an output voltage and a reference voltage that sets a clamp voltage threshold for the output voltage. The clamp output signal is employed to limit an input voltage from exceeding the clamp voltage threshold. A first switch supplies the reference voltage to the comparator. The first switch forms a portion of an intrinsic delay circuit with a first feedback path in the comparator to mitigate ripple in the output voltage. A second switch is coupled to the input voltage and a second feedback path in the comparator. The second switch forms another portion of the intrinsic delay circuit with the first switch, the first feedback path, and the second feedback path in the comparator to further mitigate ripple in the output voltage.

One aspect of the present invention includes a reference current generator circuit. The circuit includes a bias circuit configured to generate a reference current along a first current path and a second current along a second current path. The reference current and the second current can be proportional. The circuit also includes a first pair of transistors connected in series and configured to conduct the reference current in the first current path. The circuit further includes a second pair of transistors connected in series and configured to conduct the second current in the second current path. The second pair of transistors can be coupled to the first pair of transistors to provide a collective resistance value of the second pair of transistors that is proportional to temperature.
