KP464
XENSIV™ - KP464 highly sensitive barometric air pressure sensor IC with SPI interface tailored for ECU and MAF application
The Infineon KP464 is a miniaturized barometric air pressure sensor IC based on a capacitive principle. It is surface micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. Highly accurate, highly sensitive and reliable features make the sensor the ideal fit for advanced automotive applications, but also for industrial and consumer use cases.
The sensor converts a physical pressure into a 10-, 12- or 14-bit digital value and sends the information via the SPI interface. In addition, a temperature sensor is integrated on chip. Based on the received SPI command, the 10-, 12- or 14-bit temperature information will be transmitted via the SPI interface. The device has implemented a particular Power-Down Mode which allows the user to even reduce the power consumption of the device. A special reliability feature is the integrated diagnostic mode, which allows testing the sensor cells as well as the signal path. This diagnosis can be simply triggered with a SPI command. Our sensor has been primarily developed for measuring barometric air pressure, but can also be used in other application fields.
