Safety Applications
System Benefits
 Airbag systems are standard in most cars and
are mandatory equipment in many countries, saving
thousands of lives
 Infineon’s broad product spectrum supports scalability
and flexibility for building systems from 4 to over
20 firing loops
 Full range of airbag ASSPs ranging from pressure sensors
for side crash detection to driver and transceiver ICs
 High performance 32-bit AURIX™ MCU family with
dedicated safety enables integration of multiple
functions
 The parts are optimized in terms of system
interoperability as well as best price-performance ratio
 This systems are mandatory to achieve highest possible
scores in the various “New Car Assessment Programs”
(NCAP) throughout the world and are even legislated in
some countries
