eFuses & power breakers

Image of eFuses & Power breakers SubbrandElectronic fuses (eFuses) can replace larger conventional fuses or other protection devices such as resettable PTC fuses. Housed in small plastic packages, such as DFN and Flip-chip, they integrate a control logic and a power switch. eFuses provide overvoltage and overcurrent protection and programmable soft-start time. Typical applications are HDD/SSD arrays and servers as well as industrial and network hot-swap boards.

DC Power breakers provide continuous monitoring of the input power and interrupt the circuit in case of anomalous power consumption. The power limit is adjustable by the user. Used in home appliances and white goods, they optimize the design of power distribution systems, and simplify the certification flow to comply with international safety regulations.


eFuses, a smart offer for lots of applications
