Kinetic Technologies Announces Industry’s First USB Type-C Complete Port Protection Enabling Power Delivery to 140W with PD3.1 Extended Power Range (EPR) Compatibility

Thunderbolt™ Compatible CC and SBU protection IC paired with ultra-low resistance protected load switch operates up to 28V VBUS, while adding robust surge, ESD and overvoltage protection

Munich, Germany – November 15, 2022 – Power management and video/audio interface IC leader Kinetic Technologies announced two new milestone products that can increase the Power Delivery capability of USB Type-C ports to 140W, removing the barrier to expanding the range of electronic products charged via USB. The KTS1898 is dedicated to switching and protecting VBUS power, while the KTU1128 is dedicated to switching and protecting the CC1/2 and SBU1/2 lines.

The KTS1898 is a low-resistance, 5A load switch with soft-start, overvoltage, “ideal diode” reverse-current, short-circuit, over-current, over-temperature and ESD protection plus integrated surge protection of ±100V, designed to isolate and protect downstream components from abnormal VBUS voltage and current conditions. The fast reverse current protection (ideal diode) allows multiple power paths to be connected to VBUS OUT without interference.

The KTU1128 companion IC is a Thunderbolt compatible, Type-C USB data line protection and switch IC, providing low-resistance, ultra-fast OVP, and surge protection for the CC and SBU lines. Maintaining pin-to-pin compatibility with existing products, the KTU1128 increases the operating tolerance on CC and SBU lines to 32V for short-to-VBUS protection and reduces the quiescent current.

“The KTS1898 and KTU1128 are industry leading devices that allow designers to implement USB Type-C PD3.1 Extended Power Range (EPR) up to 140W and effectively address safety at the same time,” says Erik Ogren, Kinetic Technologies Senior Director of Marketing. “With the ability to withstand up to +35V on VBUS, the KTS1898 delivers the margin our customers require to build 28V systems that are designed to be safe and reliable, while the super low-resistance 25mΩ MOSFET keeps heat to a minimum, which is essential when operating at such high-power levels. The KTU1128 features the same built-in robust protection and together extends Kinetic’s lead in this application.”

KTS1898 and KTU1128 samples are available now with production starting in first quarter 2023. Visit Kinetic Technologies for further information.
