Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has expanded its automotive power distribution portfolio with the SPOC™ Wire Guard BTS80009 SWPx 1ES, a highly integrated 12 V automotive eFuse with SPI interface. As the first member of a new smart power switch family, it combines a protected high-side switch with integrated I²t wire protection, software configurability, and advanced diagnosis. The SPOC Wire Guard BTS80009 SWPx 1ES automotive eFuse provides ultrafast failure isolation in µs as well as precise current sensing, avoiding overdimensioning of the wire diameter compared with traditional melting fuses. In addition, SPOC Wire Guard devices provide real-time status, pre-warning indicators, and other diagnostics to improve vehicle availability and enable optimization throughout the vehicle’s lifecycle. SPOC Wire Guard also addresses growing needs for features supporting Advanced Driver Assistance Systems (ADAS) and enables fail-operational capabilities for L2++ to L5.
