About

XENSIV™ Barometric Absolute Pressure (BAP) sensor portfolio

Infineon XENSIV™ Barometric Absolute Pressure (BAP) sensors measure absolute pressure relative to a vacuum reference, providing accurate atmospheric and system pressure data for automotive, industrial, and consumer applications. The portfolio includes analog and digital MEMS pressure sensors with compact packages, low power consumption, integrated signal conditioning, and robust performance across a wide operating temperature range.

Depending on the application, BAP sensors provide precise pressure data for environmental monitoring, system diagnostics, altitude measurement, airflow control, battery monitoring, and thermal event detection. Available devices support different pressure ranges, interfaces, supply voltage requirements, and qualification levels, enabling designers to select the right sensor for automotive-grade systems as well as industrial and consumer applications.

BAP sensors for automotive applications

XENSIV™ Barometric Absolute Pressure (BAP) sensors support multiple automotive applications requiring accurate ambient or system pressure measurement. In engine control units (ECUs), barometric pressure data enables compensation for altitude and environmental conditions, helping optimize vehicle control strategies. Dedicated analog and digital BAP sensors are also used in pneumatic seat comfort systems, supporting pressure monitoring across standard and extended pressure ranges.

In electrified vehicles, selected BAP sensors enable battery pressure monitoring and thermal runaway detection in battery management systems (BMS) through autonomous low-power operation, pressure event detection, wake-up functions, diagnostics, and digital communication interfaces. The portfolio includes automotive-qualified devices and products designed to support functional safety-related system architectures. Refer to the individual product documentation for qualification and safety classification details.
