Freescale's Automotive DSI Airbag System*

The central component of an airbag system is a control unit that combines a 16- or 32-bit MCU with a set of local acceleration sensors. Depending on the complexity of the system, additional satellite sensors provide supplementary crash information via a standardized sensor bus, such as the Distributed System Interface (DSI). Processed sensor data is used to fire front, side and curtain airbags with specialized multi-channel squib driver circuits.

 

As an additional safety factor, highly-efficient switched-mode power supply components allow the system to keep operating for several hundred milliseconds if the battery connection is lost during an accident.

Advantages

 

  • Complete chipset targeted at airbag systems that are based on DSI standard delivers cost savings, scalability, and decreased time to market
  • Innovative MEMS-based satellite sensors and interial sensors designed for use as main crash sensor or safing sensor allow for improved performance and reduced overhead
  • Scalable Qorivva 32-bit MCU family for safety applications, up to 512 KB Flash, separate Data Flash, all with Error Correction Code (ECC)
  • Intelligent sensing technologies for front and side crash detection
  • Xtrinsic X- and Z-axis over-damped inertial satellite sensors housed in a QFN package provide a smaller footprint and more flexibility for module orientation in vehicles
  • Over-damped MEMS transducer and high resonance frequency package provide better immunity to overload conditions induced by high magnitude and frequency shocks
  • Improved system reliability against parasitc vibrations due to Freescale's overdamped MEMS transducer
  • Our Xtrinsic MMA16xx and MMA26xx satellite sensors, and the Qorivva MPC560xP and MPC574xP MCUs are SafeAssure functional safety solutions
  • Broad portoflio of 8- and 16-bit MCU for redundancy and safing functions
  • Freescale product longevity program offers up to 15-year availability for selected product
