Industrial technology manufacturer Littelfuse has unveiled 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 (3.3 V to 28 V) 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

“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 plus 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 — 5 V, 4 A, overvoltage, overcurrent protection, SOT23-3 package
- LS0505EVD22 — 5 V, 5 A, overvoltage, overcurrent protection, DFN2x2 package
- LS1205ExD33 — 18 V, 5 A, programmable current limit, output voltage clamp, DFN3x3 package
- LS2406ERQ23 — 28 V, 6 A, 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).
