Pressure Sensors Transducers Applications

• Side airbag deployment detection systems
• Pedestrian protection system activation
• Automotive crash detection modules
• Safety-critical pressure monitoring in vehicles

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix XTMA1 against official Infineon documentation to confirm package type and tape/reel specifications. Ensure compatibility with PSI5 interface requirements in the target system design. Confirm that the ISO 26262-ready status aligns with the overall system safety integrity level targets before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this component when a digital PSI5 interface is required for side impact or pedestrian protection scenarios. The wide pressure range up to 280 kPa distinguishes it from lower-range variants like the KP300. Consider the operating temperature limit of 125 °C for under-hood or high-thermal environments compared to lower-rated alternatives.

Pressure Sensors Transducers Part Context

This part belongs to the Infineon XENSIV family of pressure sensors, specifically engineered for safety-relevant automotive applications. It complements other models in the series by offering a higher maximum pressure range suitable for detecting rapid pressure changes during collisions. The digital output simplifies integration with microcontrollers supporting the PSI5 standard.

Pressure Sensors Transducers Replacement Considerations

KP300XTMA1 serves as a substitute for applications requiring a lower maximum pressure range of 126.5 kPa. Both parts share the same package and interface but differ in their upper pressure limits. Verify that the reduced range of the replacement part meets the specific detection thresholds of the intended safety application.
