Authorised distributor Mouser Electronics is now shipping the new XENSIV KP497 smart barometric pressure sensor from Infineon Technologies.
It is an advanced, highly integrated digital pressure sensor designed for demanding battery management systems (BMS) found in automotive and industrial control applications.
The XENSIV KP497 combines a precision barometric pressure sensor with an integrated one-axis accelerometer, temperature sensing, and digital interface support, delivering broad monitoring capability in a single compact package.
An absolute pressure measurement range of 20 to 250kPa with ±2kPa accuracy is suitable for detecting rapid pressure changes associated with thermal runaway events and other critical conditions in high-voltage battery packs.
An integrated z-axis accelerometer with ±2g accuracy facilitates shock and vibration detection, enhancing system diagnostics and health evaluation.
The KP497 pressure sensor also features a multi-phase, low-power autonomous state in which the sensor regularly performs pressure and/or acceleration measurements, utilising user-defined thresholds.
These thresholds, multi-stage pressure and acceleration monitoring, and programmable measurement intervals enable the device to operate independently of a host microcontroller, allowing wakeups triggered by threshold violations while reducing overall system power consumption.
Configurations are stored in the internal non-volatile memory and can be updated in-field via SPI or I2C serial interfaces. The KP497 pressure sensor can also be operated as a digital sensor via the I²C or 3-wire SPI interface.
This sensor offers 3kB of flash memory for storage and high-accuracy pressure sensing, is AEC-Q100 Grade 1 qualified for automotive applications, and is RoHS compliant.
