LITTELFUSE eFuse Protection ICs series includes four versatile circuit protection devices that provide a wide range of power input (3.3V to 28V) and integrated protection. In addition to overvoltage protection, the electronic fuses protect against overcurrent, short circuit, inrush current, reverse current, and overtemperature events with real-time diagnostics—all in one chip. Products are suitable for use in a wide range of consumer electronics and data communications interfaces. Devices provide a highly accurate current limiter, with faster response time and more integrated protection features than traditional fuses and PTCs. Devices incorporate more flexibility such as adjustable overvoltage threshold, current limiting and inrush current, along with true reverse current blocking compared to conventional power switches.
