KP276A1201XTMA1

XENSIV™ - KP276A1201 digital Turbo MAP (dTMAP) pressure sensor with SENT output and temperature sensor interface

Infineon´s KP276A1201 is a miniaturized digital absolute pressure sensor based on a capacitive principle. It is surface micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. Our sensor converts a pressure into a 12-bit digital value and sends the information via the SENT protocol (SAE J2716 revised April 2016). In addition, an interface for an external negative temperature coefficient (NTC) temperature sensor is provided. The temperature information given by the NTC is also digitized into a 12-bit value and transmitted with the SENT protocol. A special safety feature is the integrated diagnostic mode, which allows testing of the sensor cells as well as the signal path. This diagnosis is triggered by powering the device. The sensor was primarily developed for measuring manifold air pressure, but can also be used in other application fields.
