The TPD2S300 is a single chip USB Type-C port protection solution that provides 20-VShort-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 USBType-C have been released which do not meet the USB Type-C specification. One example of this isUSB Type-C Power Delivery adaptors that start out with 20 V on the VBUSline. Another concern for USB Type-C is that mechanical twisting and sliding of the connector couldshort pins due to the close proximity they have in this small connector. This can cause 20-VVBUS to be shorted to the CC pins. Also, due to the close proximity of thepins in the Type-C connector, there is a heightened concern that debris and moisture is going tocause 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 be20-V tolerant, even though they only operate at 5 V or lower. The TPD2S300 enables the CC pins tobe 20-V tolerant without interfering with normal operation by providing overvoltage protection onthe CC pins. The device places high voltage FETs in series on the CC lines. When a voltage abovethe OVP threshold is detected on these lines, the high voltage switches are opened up, isolatingthe 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 externalpins. The TPD2S300 integrates IEC 61000-4-2 ESD protection for the CC1 and CC2 pins, removing theneed to place high voltage TVS diodes externally on the connector.
