Applications

SCA3100-D04 is targeted to applications with high stability requirements. Typical applications include

  • Hill Start Aid (HSA)
  • Electronic Parking Brake (EPB)
  • Roll Over detection
  • Suspension control
  • Inclinometers
  • Motion and position measurements General Description SCA3100-D04 is a high performance three axis acce lerometer component based on VTI capacitive 3D-MEMS technology. The component integrates high accuracy microm echanical acceleration sensing together with a flexible SPI digital interface. Dual Flat Lead (DFL) housing guarantees reliable operation over product lifetime. SCA3100-D04 is designed, manufactured and tested for hi gh stability, reliability and quality requirements of automotive applications. The accelerometer has extremely stable output over wide range of temperature, humidity and vibration. The component is qualified against AEC-Q100 standard and has several advanced self diagnostics features. The DFL housing is suitable for SMD mounting and the component is compatible with RoHS and ELV directives. SCA3100-D04 is a part of VTI digital accelerometer family and fully compatible with si ngle axis accelerometers (SCA800 series) and other multi axis accelerometers (SCA2100 series and SCA3100 series).
