VTI SCA3100

VTI Automotive Digital Accelerometer Platform

The new concept offers improved performance for automotive sensing

VTI Technologies has launched the next generation of accelerometers for use in automotive electronics. The SCA8X0/21X0/3100 is a comprehensive range of sensors intended for integration into a variety of electronic systems developed for vehicle safety and control. They have been developed to combine reliability and high performance sensing with excellent cost-effectiveness and accuracy.

The new family offers acceleration and inclination sensing as a complete platform, which can have the same pin-out in one-, two- and three-axis accelerometers. Measurements in X-, Y- and Z -direction as well as any combination of two and three directions are possible. 

Application areas include Electronic Stability Control (ESC), Hill Start Assistant (HSA), Electronic Parking Brake EPB, Roll Over Detection and Electrically Controlled Suspension systems. Most of these applications require the ability to sense several directions at the same point.
