KP305XTMA1

KP305XTMA1 is an XENSIV™ pressure sensor IC for side crash detection and pedestrian protection. It provides an output proportional to the pressure change inside a crash-sensitive air volume, offering relative pressure as a digital Manchester encoded output signal for autonomous operation without additional logic ICs. The device is a pressure sensor for the detection of side crashes in passenger cars and for other pressure-based collision detection systems like pedestrian or front crash protection. In these applications, the pressure sensor is assembled in a door module located within the car's side door or connected to another crash-sensitive air volume, like a tube in the bumper of the car. When the air volume is compressed due to the collision, the device provides an output, which is proportional to the pressure change inside the sensitive air volume (∆p/p0). The amplitude of the output is independent of the ambient pressure but is dependent on the relative pressure change.
