KP300

XENSIV™ - KP300 pressure sensor IC for side crash detection and pedestrian protection

The Infineon XENSIV KP300 is a pressure sensor used for side crash detection in passenger cars. It is assembled in a door module within the car's side door and provides an output proportional to the pressure change inside the sensitive air volume (∆p/p0). The relative pressure is provided as a digital Manchester encoded output signal, enabling autonomous sensor operation without additional logic ICs in the pressure satellite.
