    BMA250E (not for new design-ins)

    The BMA250E is an advanced, ultra-small, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 10 bit digital resolution, the BMA250E allows low-noise measurement of accelerations in 3 perpendicular axes.

    On top, theBMA250E with its 2 x 2 mm² footprint integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation detection, gaming, HMI and menu browser control. Featuring a full operation current consumption of only 130 µA the BMA250E is ideally suited for mobile consumer electronic devices.

    Applications

    - Display profile switching (ff portrait/landscape, face-up/face-down switching)

    - Flat detection

    - Tap sensing function

    - Menu scrolling

    - Gaming

    - Advanced power management for mobile devices
