eFuse ICs

Conventional fuses protect circuits and prevent equipment destruction by fusing the built-in alloy parts by Joule heat when a current exceeding the rated value flows. However, these fuses have disadvantages such as uncertainty of the breaking current, slow fusing time, and the need for replacement work due to destruction by a single overcurrent. Unlike conventional fuses, the eFuse IC (electronic fuse) has a high-speed current interruption function because the built-in MOSFETs are turned off when excessive current flows. In addition, it is not destroyed by a single overcurrent and can be used repeatedly. It is advantageous in that it can incorporate various protection functions such as overvoltage protection. This product is also effective in reducing maintenance costs and recovery time for repairs.
