The TPD2S300 is a single chip USB Type-C port protection solution that provides 20-V Short-to-VBUS overvoltage and IEC ESD protection for the CC1 and CC2 pins.

Since the release of the USB Type-C connector, many products and accessories for USB Type-C have been released which do not meet the USB Type-C specification. One example of this is USB Type-C Power Delivery adaptors that start out with 20 V on the VBUS line. Another concern for USB Type-C is that mechanical twisting and sliding of the connector could short pins due to the close proximity they have in this small connector. This can cause 20-V VBUS to be shorted to the CC pins. Also, due to the close proximity of the pins in the Type-C connector, there is a heightened concern that debris and moisture is going to cause the 20-V VBUS pin to be shorted to the CC pins.

These non-ideal equipments and mechanical events make it necessary for the CC pins to be 20-V tolerant, even though they only operate at 5 V or lower. The TPD2S300 enables the CC pins to be 20-V tolerant without interfering with normal operation by providing overvoltage protection on the CC pins. The device places high voltage FETs in series on the CC lines. When a voltage above the OVP threshold is detected on these lines, the high voltage switches are opened up, isolating the rest of the system from the high voltage condition present on the connector.

Finally, most systems require IEC61000-4-2 system level ESD protection for their external pins. The TPD2S300 integrates IEC 61000-4-2 ESD protection for the CC1 and CC2 pins, removing the need to place high voltage TVS diodes externally on the connector.
