Applications enabled by X-FAB technologies

  • Power train

    Vehicle electrification brings its own share of challenges. Our high-voltage SiC solutions combined with our robust SOI technologies easily manage large voltages and current spikes to control the electric vehicle power train.

    Making internal combustion engines greener is achieved with precise integrated sensors and signal processing associated with high-power actuator and smart motor control technologies.

  • Body and convenience

    A windshield wiper seems trivial, yet its speed control and synchronization require a high-performance electronic controller. This example highlights how advanced electronics can increase the flexibility and control of car body accessories

    The flexibility extends to the car interior, where the well-being of driver and passengers can be improved through innovations such as advanced ambient lighting.

  • Chassis and driver assistance

    Autonomous driving starts with a drive-by-wire architecture. In combination with smart sensing and assistance, this enables the car to ultimately drive itself.
    Sensor fusion relies on optical, ultrasound and radio frequency (RF) signal sensing and processing served by a robust and reliable in-car network with highly resilient interfaces.

  • Infotainment

    Today‘s automobiles are interactive and connected. They are an extension of the living room and the office. Analog interfaces provide gesture recognition and haptic feedback for a safer experience. 
    With more complex data links to the vehicle, the RF interfaces require advanced connectivity channels and smart antenna management.

    Solutions we offer for automotive products

    Virtually everything X-FAB does has automotive in mind with a focus on mixed-signal and high-voltage solutions. Our high-precision and high-voltage CMOS technologies come with a full digital environment including high-quality non-volatile memories to allow a high level of integration. The sensor- and driver-dedicated circuitry can then be combined with on-chip hardware and software signal analysis.

    We support voltages from precision small signal range to demanding kV ranges with options of CMOS, SOI, SiC and GaN technologies for the most optimized circuit.

    Sensors and actuators based on dedicated modules, such as optical and MEMS modules, can be combined with the control logic in the most effective system solution using advanced packaging, multichip assembly or single-chip integration.

    All our wafers are built in our high-standard 6” and 8” high-volume facilities. Our production environment, procedures and workforce are focused on the automotive industry, and dedicated processes can be implemented on demand with our XPLUS service package.

    With their IATF16949 certification, all our fabs are suited for automotive manufacturing, and we are ready to support our customers with their specific quality requirements.

    CMOS processes with high-voltage options enable embedded control and robust interfaces

    With ample voltage capability to handle 12 V and 48 V board nets with the appropriate robustness, our CMOS platforms are tailored for automotive applications. The associated high-current capability is perfect for brushless motor and actuator drivers with adequate temperature handling for under-the-hood applications. X-FAB offers many options, such as multi-voltage architecture, low-resistivity metal layer and high-precision analog devices on bulk and SOI substrate. We provide technologies for sensing and controlling with the appropriate quality, reliability and endurance for your applications.
