TPD4S311/TPD4S311A USB Type-C Port Protector

Texas Instruments TPD4S311/TPD4S311A USB Type-C™ Port Protector is a single-chip USB Type-C port protection device with 20V Short-to-VBUS overvoltage and IEC ESD protection. Many products and accessories for USB Type-C have been released that do not meet the USB Type-C specification. One example is USB Type-C Power Delivery adaptors that only place 20V on the V_BUS line. Another concern for USB Type-C is that mechanical twisting and sliding of the connector could short pins due to the devices' proximity to this small connector. This issue can cause 20V V_BUS to be shorted to the CC and SBU pins. Also, due to the proximity of the pins in the Type-C connector, there is a heightened concern that debris and moisture will cause the 20V V_BUS pin to be shorted to the CC and SBU pins.
