The RT1738E is a USB Type-C interface overvoltage protection IC. It protects against the high voltage shorted to VBUS to adjacent pins of CC/SBU up to 28V due to USB Power Delivery (PD), allowing VBUS from 3.3 to 21V sourcing. The RT1738E integrates ESD protection compliant with IEC61000-4-2, with contact discharge of ±8kV on CON_CC1/CON_CC2, and D1/D2, and ±6kV on CON_SBU1/CON_SBU2. The surge immunity level of CON_CC1 /CON_CC2 is up to ±35V. Additionally, the ultra-fast OVP response time of 60ns can protect the system side of the application IC from damage.The RT1738E is available in a 3×3mm WQFN package. The recommended junction temperature range is −40°C to 125°C, and the ambient temperature range is −40°C to 85°C.
