Abstract
In electronic systems, the downstream circuitry may be damaged by overcurrent and overvoltage events. Therefore, there is provided a dual protection device for protecting electrical components in electronic systems. The protection device includes a mechanical fuse in conjunction with an electronic fuse, eFuse, the two components connected in series, together protecting against overcurrent events on two levels. The mechanical fuse provides high overcurrent protection, realising fast and reliable protection at high overcurrent events, and the electronic fuse provides low overcurrent protection, realising accurate and resettable protection for low overcurrent events.
