The latest eFuse Protection ICs
Featured Product from Littelfuse, Inc.
Littelfuse Expands eFuse Protection ICs Series to Address More Diverse Demanding Applications
Provides single-chip protection, control, and sensing features ideal for 5V-28V applications.
The latest eFuse Protection ICs utilize an innovative design ideal for a wide range of power inputs (3.3V to 28V) with highly integrated protection. These semiconductor-based electronic fuses provide robust overvoltage, overcurrent, short circuit, and inrush current protection. Additional features include reverse current blocking, under voltage lockout (UVLO), soft start, and overtemperature protection with real-time diagnostics—all in one compact chip. View the video.
The latest eFuse Protection ICs are ideal for use in a wide range of electronics designs, including:
- 5V Applications
- 12V Applications
- 24V-28V Applications
"The expanded eFuse Protection ICs product line delivers clear performance advantages for electronics designers,” said Bernie Hsieh, Assistant Product Manager of the Protection Semiconductor Business team at Littelfuse. “Compared to traditional fuse, PTCs, power switches, and discrete solutions like Schottky diode and MOSFET combinations, the eFuses provide exceptional integration, adjustability, flexibility, and reliable protection features in highly compact form factors that save PC board space."
The eFuse Protection ICs offer the following key benefits:
- Accuracy and integration – Provide faster response time, highly accurate current limiting, and more integrated protection, control, and sensing features than traditional fuses and PTCs.
- Programmable and customized, designed to user request – Incorporates more flexibility including adjustable overvoltage threshold, current limiting, and inrush current, along with accurate reverse current blocking compared to conventional power switches.
- Speeds up time-to-market – Reduces the design-in phase, printed circuit board (PCB) space requirements, BOM cost, and time-to-market in comparison to typical discrete solutions (e.g., hot-swap controller + MOSFET).
- Maximize Equipment Uptime – Improves product reliability, increases battery life, lowers repair costs, and lengthens overall product lifetime.
