Our comprehensive family of XENSIV™ sensors includes a wide choice of pressure sensors tailored specifically to the needs of automotive, industrial and consumer sectors. Offering rapid time-to-market, our XENSIV™ portfolio ensures the perfect fit for all performance and integrity needs. Featuring analog and digital interfaces, these sensors give customers a high degree of design flexibility, while also enabling manufacturers to meet evolving market and compliance demands.
With their small size and energy-saving designs, XENSIV™ sensors are ideal for a wide range of consumer applications, including multicopters and drones, health and fitness trackers (in smart watches for instance), outdoor and indoor navigation systems and smart home appliances such as air flow control. They are also increasingly popular in the healthcare space. On the automotive front – where safety and high precision are essential – many manufacturers rely on our XENSIV™ products for tire pressure monitoring system (TPMS), seat comfort, side crash detection, pedestrian impact detection and weather applications.
Barometric (BAP) & Manifold (MAP) sensors – highest accuracy and precision on the smallest footprint and energy bill
Highest quality and accuracy for safety-relevant automotive, industrial or consumer lifestyle applications
Typical safety-related automotive pressure sensing applications such as side impact and pedestrian protection call for the highest quality and accuracy standards with full ISO 26262 compliance. Our XENSIV™ family includes integrated pressure sensors that tick all these boxes with PSI5 peripheral sensor interfaces for safety-critical use cases.
Our digital interface portfolio also comes with serial parallel interfaces (SPI) for common powertrain and body applications such as barometric air pressure (BAP), fuel vapor and seat comfort sensing. Looking to the future, XENSIV™ even includes sensors that comply with the single edge nibble transmission (SENT) protocol with short PWM code (SPC) functionality to support upcoming engine management products such as manifold absolute pressure sensors (MAP), turbo MAPs (with a negative temperature coefficient or NTC) and secondary air valves.
Discover our highlight product dedicated for 2-wheelers: KP212 enables lower CO2 emissions, as well as lower fuel consumption, which makes it the right fit product worldwide to fulfill emission regulation requirements such as CN6 and Bharat 6. Of course these sensors can also be used in industrial control, consumer application and medical applications.
Small size, low power consumption and highest precision for air pressure sensing in consumer and IoT applications
Our XENSIV™ family of digital absolute barometric pressure sensors gives designers the best choice when it comes to mobile and wearable devices. Highlights include small form factors to facilitate system integration, highest precision and relative accuracy over a wide temperature range, fast read-out speeds via the serial I2C/SPI interface, and low power consumption to ensure longer battery lifetimes.
All of our air sensing solutions have a FIFO buffer that can store the last 32 measurements. Since the host processor can remain in sleep mode for a longer period between readouts, the FIFO buffer can reduce system power consumption further.
When can I use a XENSIV™ absolute pressure sensor for consumer applications?
Our DPS310 barometric pressure sensor is the number one option for applications where power consumption and precision are critical. If environmental protection is also required, our ultra-small digital barometric air pressure sensor DPS368 is the best match as it can be used in harsh environments due to its robustness against water, dust and humidity. In addition, it facilitates board handling in assembly lines.

How XENSIV™ safety pressure sensors make cars safer – PSI5 PRO-SIL™ ready pressure sensors for side crash detection and pedestrian protection
Typical safety-related automotive pressure sensing applications such as side impact and pedestrian protection call for the highest quality and accuracy standards with full ISO 26262 compliance. Every year thousands of pedestrians are severely injured in traffic due to slow or failing sensing elements. Our Infineon XENSIV™ safety pressure sensor family includes integrated pressure sensors that tick all these boxes with PSI5 peripheral sensor interfaces for safety-critical use cases. Our sensors supprt new safety systems, increasing the protection of pedestrians and car occupants in the event of a collision.
The Infineon safety pressure sensors deliver a reliable signal with benchmark reaction time in the industry, even though only 2 sensors are needed, the exact impact position over the complete front side can be calculated granting reduced system cost.
SP40+ tire pressure sensor for Tire Pressure Monitoring Systems (TPMS)
Infineon XENSIVTM tire pressure sensors provide a very high level of integration and are optimized to perform all of the functions necessary to implement a state-of-the-art module for Tire Pressure Monitoring system. With its integrated micro controller, sensors and convenient peripherals, the SP40+ needs the addition of only a few passive components and a battery to form a complete TPMS sensor assembly.
SP40+ measures pressure, radial acceleration, temperature and supply voltage and is certified as a green package compliant with RoHS. SP40+ comes with a pressure-auto-ranging feature, providing best-in-class pressure-accuracy in the range from 100 to 1400 kPa, making it the ideal choice for all kind of vehicles from passenger cars to heavy truck applications.
