High-speed USB dual SPDT switch carries overvoltage protection

Kinetic Technologies announced the launch of KTU1001, the high-speed USB dual SPDT switch with overvoltage protection. The KTU1001 reinforces the commitment Kinetic Technologies holds to port protection and further expands the company’s data line protection portfolio.

“USB Type-C brings many benefits to users; however, it creates many potential fault conditions for OEM designers to protect against. Protecting system ICs downstream from the USB port is critical, and the KTU1001 brings the market’s highest level of OVP protection,” says Kinetic Technologies Vice President David Nam. “The KTU1001 provides significant power savings compared to competing solutions, which is important for mobile devices–and the added benefit of ultra-fast fault OVP maintains safe voltages, even under fault conditions.”

USB Type-C Power Delivery can negotiate up to 20V, which creates potential destructive fault conditions if VBUS and neighboring pins are shorted. The KTU1001 operates from 2.7V to 5.5V with overvoltage fault protection up to 20V and surge rating up to 25V.

The KTU1001 only consumes 25µA yet has ultra-fast 100ns response to overvoltage conditions. The overvoltage threshold is 4.8V (typ) and the reverse-blocking switches are rated at 6Ω, 4pF and >1GHz -3dB bandwidth. Logic controls include a dedicated enable pin, independent switch ON/OFF pins, and the device features an overvoltage fault flag output.

The KTU1001’s low power consumption and ultra-small packaging make it ideal for USB interface switching and protection across smartphones, tablets, mobile devices, camcorders, digital cameras, electronics with service test modes, embedded mass storage, telecom equipment, and set-top boxes.

KTU1001 is available and shipping now. Visit Kinetic Technologies for more information.
