Build smarter and safer automotive power distribution
Software-defined fuse
Configurable I2T enables precise, fast-acting fault protection tailored to automotive zone needs—boosting safety, efficiency, and system reliability under all load conditions.
Better energy efficiency
As power budgets become more constrained, our smart eFuse high-side switches cut power loss to enable more energy-efficient zone controllers.
Comprehensive fault protection and granular diagnostics
With a digital interface, integrated ADC, and fault log, the smart eFuse high-side switches better inform predictive maintenance systems and enables centralized fault management in zone architectures.
Smart, scalable cross-platform power distribution
Our smart eFuse high-side switches offer scalable protection, remote reprogramming, and enhanced serviceability—enabling over-the-air updates and streamlined design across zonal vehicle platforms.
