Research and Markets - Infineon DPS310 Capacitive Pressure Sensor: Structure and Cost Analysis with Comparison of STMicroelectronics Pressure Sensor LPS22HB and the Bosch Sensortec BMP280

DUBLIN, Mar 20, 2017 /PRNewswire/ --

Research and Markets has announced the addition of the "Infineon DPS310 Capacitive Pressure Sensor: Structure and Cost Analysis" report to their offering.

Research and Markets Logo

The first barometric sensor from Infineon for the consumer market is targeting altitude, GPS, indoor and weather forecasting applications in portable devices. This MEMS sensor positions Infineon to compete with STMicroelectronics and Bosch Sensortec.

Infineon's DPS310 pressure-sensing device is manufactured using a proprietary MEMS technology developed for and already sold for several years in the automotive market. The sensing element in the DPS310 is based on a flexible silicon membrane formed above an air cavity with a controlled gap and defined internal pressure. The membrane is very small compared to traditional silicon micro-machined membranes. Moreover, Infineon has developed a capacitive sensor to be more accurate and less sensitive to temperature change compared to piezoresistive solutions.

For the DPS310, Infineon has introduced two important innovations. The first is a two-die solution more scalable than the monolithic solution used for some automotive pressure sensors.

The second innovation is a plastic metallized lid to replace the classic metal lid. The device comes in a tiny 2×2.5×0.9mm HLGA molded package.

The report presents a detailed analysis of the sensor's structure and cost. Comparison with the characteristics of the STMicroelectronics pressure sensor LPS22HB and the Bosch Sensortec BMP280 highlights differences in technical choices made by the companies.
