STi²Fuse smart high-side controllers for 48 V automotive architectures
Safety, intelligence, flexibility
Driving the transition to 48 V power distribution systems
Driving the transition to 48 V power distribution systems
STi²Fuse single-channel controllers drive the shift to 48V power systems and software-defined vehicles. The VNF1248F features advanced standby performance and integrated hardware safety for system resilience, while the VNF1048F provides smart, programmable control for main rails and zonal subsystems. Together, these controllers provide the essential flexibility and digitalization required for modern, high-voltage automotive architectures.
