What is the semi-conductor fuse eFuse IC?

Reusable fuse IC made of semiconductor.
Abundant Function

The eFuse IC has a high-performance, high-precision protection function built into one package, which is not found in conventional fuses.
It can be used repeatedly, reducing maintenance costs and recovery time for repairs.

This is the product lineup list.
We plan to expand our lineup of products with a wide range of  input voltage and packages in the future.
