Conventional glass tube fuses and chip fuses have a structure that stops the current by melting the internal metal with heat when an overcurrent occurs and then breaking the wire.
Therefore, it will be broken at one time, and parts replacement, etc. must be carried out in order to operate it again.
On the other hand, eFuse IC shown on the right can be used repeatedly because the current is detected with high accuracy by the internal overcurrent circuitry to stop the internal MOSFET from being turned off.
