STi2Fuse is a new family of intelligent fuse to replace standard melting fuses in automotive power distribution systems.

STi2Fuse devices enable savings on component and production costs, while extending EV range and reducing the carbon footprint of vehicles. The monitoring, control, and digital interface capabilities of these devices help automotive systems comply with ISO26262 and related Safety Integrity Levels (SIL).

New family of intelligent electronic fuses for wire harness protection

Applications

The new STi2Fuse family integrates i2-t protection and a digital interface to boost efficiency and reliability in the latest automotive zonal electronic/electrical (E/E) architectures. It also supports greater electrification and additional functions for smart driving.

Example of power distribution architecture

Product types

STi2Fuse family products consist of two kinds of devices: an integrated solution for low/mid power ranges and a gate controller for high power ranges.

Fully integrated solution to address up to 50A current loads. Smart gate driver for very high-power loads.
