Description
The KP204 is a pressure sensor for the detection of side crashes in passenger cars. In this application the
pressure sensor is assembled in a door module located within the car’s side door. When the door is compressed
due to a side impact, the KP204 provides a signal pulse which is proportional to the pressure change inside
the door Δp/p0). The height of signal pulse is independent of the ambient pressure but is dependent on the
relative pressure change. This is achieved by dividing the absolute pressure change by the ambient pressure.
The division is performed on-chip. The ambient pressure is calculated with a low pass filter from the absolute
pressure.
The sensor provides the relative pressure as a digital Manchester encoded output signal.
This cost optimized configuration allows autonomous operation of the sensor without any further logic ICs in
the pressure satellite.
During the normal operation mode there is a continuous internal range check.

For passivation the sensor die is covered with a transparent silicone gel. Bubbles adjacent to the bond wires are
not allowed (delivery status). The bond wires have to be completely covered by gel. The surface of the gel must
be smooth.
