eFuse and hot swap controllers
System-level power path protection
Improve the reliability of your system against overvoltage, short circuit, inrush current and reverse polarity events. We’ve taken our single-chip ICs one step further than traditional eFuse devices by implementing discrete protection circuitry for the most robust device and system-level protection. Get started with our eFuse for a tiny, thermally optimized option or choose a hot swap controller with an external pass FET if your design requires more flexibility.
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) recognition.
