Accelerometers for automotive airbag systems showcased the potential for microelectromechanical system (MEMS) sensors when they were first introduced almost two decades ago. With airbags standard on US and other regions’ vehicles, and several sensors used in these systems, the application continues to spawn product advancements. Most recently, STMicroelectronics introduced a new family of high-g acceleration sensors for advanced airbag systems. Housed in a 16-pin SOIC, the digital output of the AIS1xxxDS accelerometers provides single-axis in-plane motion sensing across five full-scale ranges, from ±20 g up to ±400 g. The digital output conforms to the Distributed Systems Interface (DSI) protocol developed to interconnect sensors and actuators in automotive airbags systems.
