Digital and analog BAP sensors for accurate measurement
Barometric absolute pressure (BAP) sensors are commonly used within automotive applications such as ECU management and seat comfort. Additionally, the battery pressure sensor is an emerging application for these types of sensors, as the pressure inside the electric vehicle battery is required to be monitored for fast and robust detection of battery failure and danger for the occupants and the environment. BAP automotive sensors are available in both digital and analog designs for different applications. Analog BAP sensors produce a ratio metric analog voltage output proportional to the applied pressure, while digital BAP sensors use the digital SPI communication protocol. Our range of analog and digital BAP sensors offers excellent accuracy of up to 1.0 kPa over a large temperature span and an available pressure range from 40 kPa to 200 kPa. Moreover, our digital BAP sensors provide sensor temperature information and offer advanced power modes and sensor diagnostics features. These features, among others, ensure our barometric absolute pressure sensors function accurately with fast response times in any automotive application.
