Kinetic Technologies Launches USB VBUS Safety Management Current Limited Load Switch Supporting the Latest 28V Level of USB PD3.1 Extended Power Range (EPR) Systems
Key applications for the KTS1890 include gaming and workstation notebooks, desktop PCs, docking stations, monitors, conferencing systems, gaming consoles, and any USB Type-C Dual Role Port design with PD 3.1 EPR 28V input.
The KTS1890 is a USB VBUS safety management load switch for 15W current-source output in systems with 28V EPR current sink input. The input operating range is 2.5V to 5.5V, but the output withstands up to 35VDC at the USB port. Current limit protection (CLP) is adjustable from 400mA to 4.0A. Low on-resistance minimizes heat and voltage droop. Soft-start (SS) limits inrush current. Reverse-current protection (RCP) acts as a 20mV “ideal diode” with fast recovery.
Karl Volk, System Applications Director at Kinetic Technologies, says, “The combination of our new KTS1890, together with our KTS1898 and KTU1128 parts, provides a chipset trio setting a new benchmark for protection at every 28V USB EPR port, ensuring the quality and operational integrity of your products.”
Additional integrated safety management for the KTS1890 device includes ultra-fast over-current protection (OCP), short-circuit protection (SCP) during and after soft-start, over-temperature protection (OTP), and integrated transient voltage suppression (TVS) for IEC industry standard ±30kV ESD and ±130V surge protection.
