KTU1133: 48V Extended Power Range (EPR) USB Type-C/PD Port Protector IC Integrating VBUS Level Shift Circuit and Blocking NFET Gate Driver in 3x3mm Package

San Jose, Calif. – September 9, 2025 – Power management leader, Kinetic Technologies, is expanding its USB Data Line Protection portfolio with the introduction of KTU1133, a single-chip, highly integrated solution for USB 48V EPR Type-C Power Delivery (PD) which significantly reduces both solution cost and size. KTU1133 integrates the industry’s first automatic VBUS level shift circuit and external blocking NFET gate driver, allowing SPR-rated PD controllers to safely operate in EPR systems.

Erik Ogren, Senior Director of Marketing at Kinetic Technologies, says, “The KTU1133 Safety Manager is an advanced 48V EPR device representing a major new milestone, allowing OEM products to deliver and receive more than 100W. However, this brings new technical challenges to solve when protecting those higher voltage USB ports.  This next generation product is designed with upgraded performance to meet the IEC standard for surge protection as well as having the fastest Over Voltage Protection response times, providing a higher level of protection.”.

The CC1/2 switches have low on-resistance for passing VCONN power up to 1.25A. During dead battery conditions, optional-use internal 5.1kΩ resistors automatically pull down on CC1/2 to ensure that the up-stream source provides 5V on VBUS.

Key applications for the new KTU1133 include Mobile Workstations and Gaming Notebooks / PCs, Docking Stations, Conference Systems, Monitors, Tools, E-Bikes, Battery Power Stations, and any device with USB Type-C Port up to EPR 48V/5A, 240W.
