KTU1001AEVA-TR

Overview

The KTU1001AEVA-TR is a USB Hi-Speed dual SPDT switch with overvoltage protection, manufactured by Kinetic Technologies. It supports data rates up to 480 Mb/s and operates within a supply voltage range of 2.7 V to 5.5 V. The device features reverse-blocking back-to-back MOSFETs, a typical on-resistance of 6 Ω, and an on-capacitance of 4.0 pF. It includes an active-low enable pin and a fault flag output for system monitoring. The component is housed in a WLCSP-12 package measuring 1.17 mm x 1.57 mm and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates reverse-blocking back-to-back MOSFET switches for bidirectional current blocking when disabled.
• Provides overvoltage protection up to +20V DC with surge tolerance up to +25V.
• Features an active-low fault flag output to alert the system processor of overvoltage events.
• Supports independent control bits for each switch pair alongside a shutdown enable function.

Procurement Notes

Verify that the ordering suffix matches the required package and temperature grade. Confirm the specific revision level against the latest manufacturer documentation to ensure compatibility with design requirements. Check for any updates regarding RoHS compliance status or packaging variations before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-speed USB signal switching with integrated fault protection. Consider the ultra-small WLCSP-12 footprint for space-constrained mobile designs. Evaluate the need for reverse-blocking capabilities compared to standard switches like the KTU1000. Ensure PCB layout guidelines are followed to maintain signal integrity at high frequencies.

FAQ

How does the KTU1001AEVA-TR handle overvoltage conditions?

The device disables the switches to a high-impedance state if the COM input exceeds the overvoltage threshold, typically 4.8V, and asserts the active-low FLAG output to alert the system controller.

What is the maximum data rate supported by this switch?

The KTU1001AEVA-TR is specified for USB High-Speed applications, supporting data rates up to 480 Mbps.
