New Design Features in eFuse Bring Automotive Precision in Overcurrent Protection

Circuits used in myriad of electronics and power systems have undergone some interesting innovations in the functionalities over the years. Changing requirements of power distributions such as multi-voltage power distribution have preceded the evolution of the eFuse market. Stridently, integrated circuit protection solutions aimed at reducing the incidence of short circuits have attracted widespread adoption. Since its development by IBM in 2000s, the scope for eFuse has been steadily expanding. In part, this is due to rise in number of sensitive loads in wide range of applications such as circuits used for data servers, and many mission-critical industries.   

 Active circuit protection mechanisms need to get more precise and responsive. The number of components used in the circuitry should reduce. eFuse technology has been rising in commercialization to offer advanced protection for circuits against inrush current, overcurrent, reverse current, reverse polarity, and overvoltage. 

Need for customizable circuit-breaker operation in current protection has spurred the preference of products in the eFuse market over the existing discrete circuit protection solutions. The risk of current surges and damages from inrush current has led manufacturers of consumer and commercial electronics to adopt eFuses.
