Dummy fuse device, electronic apparatus including the dummy fuse device, and method of operating the dummy fuse device

摘要

A dummy fuse device includes a switching unit electrically conducted to perform electrical signal transfer when it is determined that electrical signal transfer through a main fuse is failed, and a dummy fuse opening to block the electrical signal transfer when the voltage of the electrical signal supplied through the electrical conduction of the switching unit exceeds a predetermined level. An electronic apparatus including the dummy fuse device may also include the main fuse, a power supply unit, and a circuit. A method of operating the dummy fuse device is further provided.
