Automotive suppliers are developing an important application to automatically contact emergency services in the event of a collision or vehicle problem. The application can supply potentially life-saving details such as the location of the vehicle and the estimated severity of the problem or accident to emergency service operators. Examples of these services include
In addition to all of the amazing safety innovations already built into today s vehicles, this tiny sensor may play a vital role in protecting the car s occupants, said
The major parameters in estimating the severity of a collision include the decelerations that occurred in all three dimensions at the moment of impact; for instance, the ERA Glonass specification for the Russian market requires that longitudinal accelerations up to +/-24g must be measurable with sufficient accuracy. The AIS3624DQ brings all the benefits of ST s market-proven stacked-chip technology to the automotive market.
Key features of the AIS3624DQ include: Selectable full-scale range: 6g / 12g / 24g, 6-bit data output, Two digital output lines (interrupt generators), 9 user-selectable Output Data Rates (ODR), Power down, low power and normal power modes, SPI and I2C digital output protocols, Embedded self-test, up to 10,000g shock survivability, Temperature range: -40°C +105°.
Housed in a QFN 24L (4x4x1.8 mm3) package, the AIS3624DQ is currently available as engineering samples. Volume production is scheduled for Q4 2014, with an anticipated price of
