Backup fuse device, electronic apparatus including the backup fuse device, and method of operating the backup fuse device

摘要

A backup 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 backup 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 backup fuse device may also include the main fuse, a power supply unit, and a circuit. A method of operating the backup fuse device is further provided.
