Marking
Each device is marked with a human readable code on the side of Pins 5 to 8. This code
contains the supplier logo, a date code, wafer lot number and an offset code.
Product Description
The KP100 is an absolute pressure sensor with SPI interface for side airbag
applications. The basic accuracy including temperature drift is ±5%. The KP100 offers
some diagnosis features in order to allow a sensor status analysis.
