Abstract
An electronic fuse (eFuse) implements current limiting or fault interruption through current sensing, control logic, and power-semiconductor switches, and may integrate overvoltage protection, thermal shutdown, inrush-current suppression, reverse-current blocking, and status reporting. Its protection mechanism, recoverability, and system integration differ from those of conventional fuses that operate by melting a fuse element. IEC 60127, IEC 62368-1, UL 2367, and IEC 60947-10 address miniature fuse-links, IC current limiters, solid-state overcurrent protectors, and semiconductor circuit-breakers, respectively; however, they differ in scope and assessment objectives, and no unified product-level framework currently covers board-level low-voltage DC eFuses. By comparing standard clauses and analyzing representative protection modes, this paper discusses the product definition, ratings, protection modes, and test boundaries of eFuses, and proposes a test system centered on continuous-current carrying, overcurrent, short-circuit, repeated operation, and post-test functional verification. The results provide technical support for the development of a national standard and future proposals for international standardization.
