The TPD6S300A is a single-chip USB Type-C port protection device thatprovides 20-V Short-to-VBUS overvoltage and IEC ESD protection.
Since the release of the USB Type-C connector, many products and accessories for USBType-C have been released that do not meet the USB Type-C specification. One example of this is USBType-C Power Delivery adaptors that only place 20 V on the VBUS line.Another concern for USB Type-C is that mechanical twisting and sliding of the connector could shortpins due to the close proximity they have in this small connector. This can cause 20-VVBUS to be shorted to the CC and SBU pins. Also due to the proximity of thepins in the Type-C connector, there is a heightened concern that debris and moisture will cause the20-V VBUS pin to be shorted to the CC and SBU pins.
These non-ideal equipments and mechanical events make it necessary for the CC and SBUpins to be 20-V tolerant, even though the pins only operate at 5 V or lower. TheTPD6S300A enables the CC and SBU pins to be 20-V tolerant without interferingwith normal operation by providing overvoltage protection on the CC and SBU pins. The device placeshigh voltage FETs in series on the SBU and CC lines. When a voltage above the OVP threshold isdetected on these lines, the high voltage switches are opened up, isolating the rest of the systemfrom the high voltage condition present on the connector.
Finally, most systems require IEC 61000-4-2 system level ESD protection for externalpins. The TPD6S300A integrates IEC 61000-4-2 ESD protection for the CC1, CC2,SBU1, SBU2, DP, and DM pins, eliminating the need to place high voltage TVS diodes externally onthe connector.
