Summary

The automotive industries are now into electronics applications in which embedded systems are already part of its major components. In this design, it features the Peripheral Sensor Interface 5 (PSI5), which is the most efficient standard interface of sensors and electronic control units in automotive. It supports complete airbag system that includes system power mode control, supplies for squib firing, satellite sensors, and local Electronic Control Unit (ECU) sensors and ECU logic circuits. It has dedicated safing state machine that complements the airbag's MCU hardware/software safing approach. The system itself is capable of diagnostics and self-protection.


The design is comprised of MCZ33789 Freescale airbag system basis chip that manages the entire airbag partitions and some major components like squib driver IC, SPI communications with MCU, accelerometer sensor, satellite sensors, and dc sensors for monitoring. The squib driver IC supports air bag modules and seat belt retention that functions with accelerometer sensor. The MCU provide the connection of airbag system with the entire electronic applications of the vehicle. The LC filters are provided to ensure frequency range.



The design is used in different airbag system in which it optimizes the capability of providing safety to users. It can be used for further development of safety system in automotive and other vehicle that is prone to crash or collisions. It can help save lives during accidents.
