Compared with conventional fuses, eFuse IC has the advantage of superior protective performance.

Comparing with repeatedly usable conventional fuses, such as poly fuses, eFuse IC has the advantage of excellent accuracy of overcurrent protection and high protection speed.

In addition, it has built-in protection functions such as overvoltage and Reverse Current Bloking (RCB) function.

The efuseIC itself is larger than the chip fuse, but eFuse IC becomes overwhelmingly small in the total mounting area including the protective functions of peripheral ICs and components, such as overvoltage and slew-rate control.

Although a cost of an eFuse IC is higher than a conventional fuse, considering the total cost, such as integrating protective functions and eliminating maintenance work, we believe that eFuse IC will be low.
