RT1735 - Richtek

RT1735 USB Type-C 28V EPR Protector

The RT1735 is an USB Type-C interface overvoltage protection IC. The RT1735 protects the high voltage shorted to VBUS to adjacent pins of CC/SBU up to 28V due to USB Power Delivery (PD), which allows VBUS from 3.3 to 28V sourcing. The RT1735 is integrated with the protection against ESDs as per IEC61000-4-2 standards, with contact discharge of 8kV on CON_CC.
