Learn the basics and more advanced application concepts for implementing eFuse protection ICs

Accomplish straightforward system protection with fully integrated eFuses

eFuses are highly integrated ICs that offer device and system-level protection at the input or the output. Traditionally, complete power path protection circuitry was accomplished with a handful of discrete components – components that can use up to 70% greater board space, introduce unnecessary design hurdles, and potentially slow your time to market if UL recognition is required. Those problems are eliminated with our fully integrated eFuses that include over current, over voltage, reverse polarity and more essential protection functions.
