RT1735 - USB Type-C 28V EPR Protector

Datasheet Summary

Description

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.

RT1735 USB Type-C 28V EPR Protector with CC and SBU Short to VBUS Overvoltage and IEC ESD Protection 1 General Description 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_CC1/CON_CC2, D1/D2 and CON_SBU1/ CON_SBU2. The surge immunity level of CON_CC1/CON_CC2 and CON_SBU1/ CON_SBU2 is up to 36V. Besides, the ultra-fast OVP response time of 100ns can protect the system side of application IC from damage. The RT1735 is available in a 3x3mm WQFN package.
