eFuse and hot swap controllers
Elevate your design's performance with our comprehensive portfolio
Our power protection devices accelerate the design process by integrating the functionality of common discrete protection components like diodes, PFETs, PTC transistors and fuses into an all-in-one solution. Improve the reliability of your system against overvoltage, short circuit, inrush current control and reverse polarity events. Get started with an eFuse for a tiny, thermally optimized solution or choose a hot swap controller with an external pass FET if your design requires more flexibility.
Robust power path protection
An eFuse is a fully integrated protection device that protects against short circuit, inrush, overvoltage or reverse polarity events. Hot swaps provide similar protection for greater than 15A current rating requirements.
Eliminate the complexity of selecting and optimizing your pass FET and discrete protection components. With our integrated solutions, you can reduce your PCB area by up to 70%.
Reduce circuit design and testing time by selecting eFuses that meet the criteria for various safety and performance certification standards such as Underwriters Laboratories (UL) certification.
