KP106
Integrated Pressure Sensor IC
for Side Crash Detection
Application
The KP106 is a pressure sensor for the detection of side crashes in
passenger cars.
In this application, the pressure sensor is assembled in a module
located within the car’s side door. 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
■On chip current modulator
■On chip voltage regulator
■User specified protocol
■EE-PROM for ID number, calibration and mode selection
■Synchronous or asynchronous data transmission
■2 wire interface and SPI interface available
■Online self test
■Reverse polarity protection

The surface micro-machined capacitive pressure sensor KP106 is designed to
provide the relative pressure as a digital Manchester encoded output signal.
This configuration is optimal for a single IC satellite system, where no further logic
IC is used in the door module.
The sensor IC is mounted in an 8-pin plastic SMD PG-PSOF-8-12 package.
First engineering samples available in November 2005.
