ST’s e-Compasses include combo solutions built around a 3-axis digital accelerometer with a 3-axis digital magnetic sensor in a single LGA package, as well as standalone 3-axis digital magnetic sensors for designing solutions where the magnetic sensor must be located in a specific position on a printed circuit board.

Designed to accurately detect the direction and magnitude of external magnetic fields, ST’s e-Compasses use accelerometer measurements for tilt compensation, thus ensuring very accurate compass headings even when handheld or mobile devices are inclined.

ST’s e-Compasses combine a high-performance low power 3D accelerometer and 3D magnetometer with high dynamic range and temperature offset compensation. They offer 3 mgauss resolution and a wide range of full scales selectable by the user: from ±2 to ±16 g for acceleration and from ±4 to ±50 gauss for magnetic fields.

ST’s e-Compasses include smart power functions to minimize current consumption and an embedded self-test feature that allows the user to check that the sensor functions correctly in the final application

The full range of products offers new possibilities for advanced navigation and location-based services in increasingly portable consumer/industrial devices such as tilt-compensated compasses, map rotation, intelligent power-saving for handheld devices, gaming and virtual reality input devices, position and free-fall detection, motion-activated functions, pedometers, display orientation, impact recognition and logging, vibration monitoring and compensation.
