Chicago, Illinois. Littelfuse released four flexible circuit protection devices in the eFuse Protection ICs product line. The semiconductor-based eFuse Protection ICs are developed for a variety of power inputs including 3.3V to 28V with reliable embedded security. The fuses protect from inrush current, overvoltage, overcurrent, and short circuit. Real-time diagnostics is supported as well as under voltage lockout (UVLO), overtemperature protection, reverse current blocking, and soft start.
Flexibility is important when designing, the devices enable developers to adjust and limit current as their environment requires. "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."
