Overview

TPD4S481-Q1 is a single-chip USB Type-C port protection device that provides 48V VBUS short-circuit overvoltage protection and IEC ESD protection. Since the release of the USB Type-C connector, many USB Type-C products and accessories have been introduced that do not comply with the USB Type-C specification. Another issue with USB Type-C is that the close pin spacing within the small connector means mechanical twisting and sliding of the connector can cause pin short circuits. Such mechanical twisting and sliding can short 48V VBUS to the CC and SBU pins. Additionally, due to the close pin spacing within the Type-C connector, debris and moisture are more likely to cause the 48V VBUS pin to short to the CC, SBU, or USB2 pins. These mechanical events and non-compliant devices require CC and other pins to withstand 48V even when operating at only 5V or lower. The TPD4S481-Q1 enables the CC, SBU, and USB2 pins to withstand 48V by providing overvoltage protection on the CC and SBU pins without interfering with normal operation. The device places high-voltage FETs in series on the SBU and CC lines. For systems that do not use alternate mode with SBU communication, the SBU pins of the TPD4S481-Q1 can be used to protect the USB2 data lines. When a voltage exceeding the OVP threshold is detected on these lines, the high-voltage switch opens, isolating the rest of the system from the high-voltage condition present at the connector. Finally, the external pins of most systems require IEC 61000-4-2 system-level ESD protection. The TPD4S481-Q1 integrates IEC 61000-4-2 ESD protection for the CC1, CC2, SBU1, and SBU2 pins, eliminating the need for additional high-voltage TVS diodes placed outside the connector.
