The KTU1133 provides safety management for USB PD3.1 48V EPR ports with comprehensive protection of the CC and SBU data lines. All four data lines include 63VDC withstand for short-to-VBUS fault events in the connector and integrated transient voltage suppression (TVS) for IEC surge protection and IEC level-4 ESD protection. Fast over-voltage protection (OVP) isolates downstream system circuits during fault events.

The integrated VBUS level shift circuit and external blocking NFET gate driver allow SPR-rated PD controllers to safely operate in EPR systems. The KTU1133 is packaged in RoHS and Green compliant 20-pin 3mm x 3mm WQFN package
