Asahi Kasei Electronics and Silicon Austria Labs Successfully Validate eFuse Technology in Automotive High-Voltage Applications
🟦eFuse Improves Safety of SiC/GaN Power Devices
Asahi Kasei Electronics and SAL have successfully jointly verified eFuse technology for SiC power devices. This technology has the potential to significantly improve the safety of systems such as car chargers, as well as reduce parts and maintenance costs.
🟦 Why do you need a high-speed eFuse?
In high-voltage applications such as electric vehicles, there is a growing shift to power devices using next-generation semiconductor materials such as SiC and GaN to achieve higher efficiency. However, SiC/GaN power devices are more expensive than Si devices and can be damaged if not quickly protected in the event of an overcurrent.
Conventional fuses may not be able to protect the device due to the long shut-off time. The eFuse has a faster response time than conventional fuses and can instantly shut down circuits when it detects abnormalities such as short circuits or overcurrents.
🟦Summary
Verification of Asahi Kasei Electronics and SAL to safely protect SiC/GaN power devices and contribute to improving overall system performance with fast response speed and high-precision current limiting functions that could not be achieved with conventional fuses
Conventional fuses have the problem that there are large individual differences, and it is difficult to extract the limit performance to ensure a safety margin. On the other hand, the eFuse maximizes the performance of the device while ensuring higher safety than conventional fuses due to its fast response speed and high-precision current limiting function.
