Freescale Semiconductor offers two airbag system solutions for the emerging Peripheral Sensor Interface 5 (PSI5) protocol, including an inertial satellite sensor family and a mixed-signal analog IC. The company also complements these products with the addition of an electronic control unit (ECU) inertial sensor family. Leveraging its SMARTMOS technology for a high level of system integration available worldwide, Freescale’s PSI5 airbag system solutions include the micro-electromechanical (MEMS)-based MMA5xxxW satellite accelerometer portfolio and the MC33789 airbag system basis chip. The MEMS-based MMA68xxW dual-axis serial peripheral interface (SPI) inertial sensor for the main ECU facilitates a complete airbag system solution. According to Freescale, the technology enables a reduction in complexity and development time of airbag systems while improving reliability.
