The dual-axis SMA560 model for airbag control units marks Bosch’s entry into the fifth generation of micro-mechanical acceleration sensors. As opposed to sensors of the previous generation, this new model, in its SOIC8 housing, combines space savings of more than 40 percent with an unprecedented variety of functions. This means that circuit designers can assign one of four measuring ranges to each sensing axis independently. Via the serial peripheral interface, the sensor outputs the measuring values in either Bosch-SPI or Open-SPI format. The SMA560 can currently be ordered as a sample. The SMA550 sensor is available with the same parameters but with only one sensing axis – both are RoHs-compliant.
