application KP106 is a pressure sensor system for the detection of side crashes in passenger cars. in this application, the pressure sensor is assembled in a module located within the cars side doors. when the door is compressed due to a side impact, the KP106 provides a signal pulse which is proportional to the pressure change inside the door. the height of the signal pulse depends on the relative pressure change. therefore the output signal is independent of the ambient pressure. features psi5 compliant / multi-protocol synchronous or asynchronous data transmission user specifed protocol available 2-wire interface with on chip current modulator for manchester communication e2prom for id number, calibration and mode selection patented online diagnoses for pressure cells and circuitry serial service interface on chip voltage regulator reverse polarity protection application circuit for the pressure sensor system pressure sensor syst em KP106 pressure satellit e receiver ic airbag ec u w w w . i n f i n e o n . c o m / s e n s o r s sensors product brief KP106 integrated pressure sensor ic for side crash detection
