TPD4S480RUKR

Power Management - Specialized Overview

The TPD4S480RUKR is a USB Type-C port protector designed for 48V Extended Power Range (EPR) applications. It provides four-channel VBUS short-circuit and overvoltage protection for CC1, CC2, SBU1, and SBU2 pins, tolerating up to 63V DC. The device integrates IEC 61000-4-2 ESD protection, eliminating the need for external high-voltage TVS diodes. Key electrical parameters include a supply voltage range of 2.7V to 4.5V and an operating temperature range from -40°C to +125°C. It features integrated FET drivers and a VBUS divider circuit to support PD controllers in EPR environments.
