DigiKey Stocks Vishay eFuse Reference Design
DigiKey announced that the EFUSE-48V100A reference design from Vishay is now available globally from DigiKey. The eFuse features TrenchFET MOSFETs and handles continuous current up to 100 amps. Operating continuously at maximum current with less than 14 watts of losses without requiring active cooling, it also features a pre-charge function and overcurrent protection.
In addition to safely connecting and disconnecting to 48-volt power sources such as high-energy battery packs, the device also features fast disconnect of loads in under 2 μs, a resettable fuse, and an adjustable current limit. It is designed to work in battery management systems, EV test environments, solar installations, industry, home automation, industrial and server computing, networking, telecom, and base station power.
The eFuse concept protects the user and the hardware in high-power applications. Given the steady increase in 48-volt eMobility applications, semiconductor-based resettable fuses like the EFUSE-48V100A are ideal for replacing mechanical relays, contactors, and non-resettable fuses.
