STi²Fuse smart high-side controllers for 48 V automotive architectures
Safety, intelligence, flexibility
Driving the transition to 48 V power distribution systems
The STi²Fuse single-channel eFuse controllers for external MOSFETs are key to driving the transition to 48 V power distribution systems. They bring exceptional flexibility to the main power rail and all zonal subsystems, empowering automotive digitalization and accelerating the shift toward software-defined vehicles (SDVs).
Our lineup includes the new VNF1248F, an advanced controller that integrates superior standby performance and dedicated hardware safety features for unmatched system resilience. This is complemented by the reliable VNF1048F smart switch, which offers programmable control for the main power rail and zonal subsystems.
Both controllers are central to enhancing the flexibility of 48 V systems in modern automotive architectures.
