Reduce cable length and weight
Smart high-side switches replace melting fuses in vehicles providing resettable outputs, configurable I2T settings and improved consistency across temperature. These features allow vehicle architects to implement configurable protection in localized zone controllers, reduce the length of wiring required from traditional fuse box implementations and reduce the wire gauge. Our smart high-side switches with accurate current sense and intelligent diagnostics allow you to implement accurate and reliable fuse replacement switches.
