Abstract
A system in a vehicle includes a first fuse connected between a power source and a load. The first fuse is an electronic fuse (eFuse) to disconnect the load from the power source via the first fuse based on detecting a failure in the first fuse. The system also includes a second fuse connected between the power source and the load, the first fuse and the second fuse being part of a cluster of fuses. The second fuse is an eFuse and the first fuse signals the second fuse to disconnect the load from the power source via the second fuse based on the first fuse detecting the failure in the first fuse without the second fuse detecting a failure in the second fuse.
