BMA222E
The BMA222E is an advanced, ultra-small, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 8 bit digital resolution, the BMA222E allows low-noise measurement of accelerations in 3 perpendicular axes.
On top, the BMA222E 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 BMA222E is ideally suited for mobile consumer electronic devices.
Applications
- Display profile switching (portrait/landscape, face-up/face-down switching)
- Flat detection
- Tap sensing function
- Menu scrolling
- Gaming
- Advanced power management for mobile devices
- Shock and free-fall detection
- Step-counting
