Littelfuse Announces eFuse Protection ICs Series

October 4, 2022

Designed for heavy-use consumer electronics, data communications, and industrial applications.

Littelfuse, Inc. has announced the new eFuse Protection ICs product line, a series of four versatile circuit protection devices. The eFuse Protection ICs utilize an innovative design that provides a wide range of power input (3.3V to 28V) and integrated protection. In addition to overvoltage protection, these electronic fuses protect against overcurrent, short circuit, inrush current, reverse current, and overtemperature events with real-time diagnostics—all in one chip.

The eFuse Protection ICs are ideal for use in a wide range of consumer electronics and data communications interfaces, including:

•Bluetooth headsets
•Wearable devices
•Tablet PCs
•Charging cables
•Battery devices
•Adapter-powered devices
•Networking
•PCs/notebooks
•Datacom power systems
•Fan power controls
•HDD and SSD storage drives
•Industry 12V/24 power input/output

“The eFuse Protection ICs provide today’s electronics designers with significant flexibility by integrating robust circuit protection, sensing, and control in a single chip,” said Bernie Hsieh, Assistant Product Manager of the Protection Semiconductor Business team at Littelfuse. “Providing a low power consumption, high accuracy current limiting circuit with quick response time makes them a win-win-win for many portable electronics and datacom applications.”

The eFuse Protection ICs offer these key benefits:

•Provides a highly accurate current limiter, with faster response time, and more integrated protection features than traditional fuses and PTCs
•Incorporates more flexibility such as adjustable overvoltage threshold, current limiting, and inrush current, along with true reverse current blocking compared to conventional power switches
•Reduces the design-in phase, PC board space requirements, BOM cost, and time-to-market when versus typical discrete solutions (e.g., hot-swap controller + MOSFET)
•Improved product reliability, increased battery life, lower repair costs, and lengthened overall product lifetime

The eFuse Protection ICs are available in the following series:

•LS0504EVT233 – 5V, 4A, overvoltage, overcurrent protection, SOT23-3 package
•LS0505EVD22 – 5V, 5A, overvoltage, overcurrent protection, DFN2x2 package
•LS1205ExD33 – 18V, 5A, programmable current limit, output voltage clamp, DFN3x3 package
•LS2406ERQ23 – 28V, 6A, true reverse blocking, fast role swap, QFN2.5x3.2 package

Availability

The eFuse Protection ICs are available in tape and reel format in quantities of 3,000 (LS0504EVT23, LS0505EVD22) or 5,000 (LS1205ExD33, LS2406ERQ23). Place ample requests through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
