Littelfuse is a diversified industrial technology manufacturing company empowering a sustainable, connected and safer world. Across over 20 countries, and with approximately 18,000 global associates, it partners with customers to design and deliver innovative, reliable solutions.
Embedded systems and IoT solutions are a key market for Littelfuse, offering a full production solution.
Littelfuse has released four versatile circuit protection devices in the eFuse Protection ICs product line.
The latest eFuse Protection ICs utilise an innovative design suitable 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.
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 customised, 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, bill of materials cost, and time-to-market in comparison to typical discrete solutions (e.g., hot-swap controller plus metal-oxide semiconductor field-effect transistor).
- Maximise equipment uptime — Improves product reliability, increases battery life, lowers repair costs, and lengthens overall product lifetime.
