Test bench, modeling, simulation results and virtual development and validation of electronic fuses.
In conventional safety systems, the off state can be assumed to be safe. With ADAS, this is no longer automatically the case. This makes it necessary to adopt new approaches to fuse protection, which will subsequently spread to other industries.
Traditionally, the vehicle electrical system was protected by sacrificial fuses. These reliably disconnect the power supply in the event of overcurrents, but in the process, they switch off individual components or, depending on their position, even whole sections of the vehicle electrical system. The eFuse offers various options for maintaining functionality in the event of a fault.
In a presentation at the May 2025 EEHE International Conference, Fraunhofer Institute for Integrated Circuits IIS Division Engineering of Adaptive Systems EAS presented the “Measurements and Simulation-Based Characterization of eFuses.”
