MMA845 Digital Triaxial Accelerometer Precision Tilt 3-Axis Module

MMA8452Q was designed as a 3-Axis Accelerometer Module based on the three-axis accelerometer IC MMA8452. This capacitor-type micro mechanical accelerator offers a 12-bit resolution with smart, low power consumption. Hence performed as a  rich embedded system function, with additional flexible programmer options, up to two interruptions. Thus these Embedded interruptions capable of saving more power,  release the MCU from the endless query load. MMA8452Q supports a wide sensitivity range from ±2g/±4g/±8g for choosing. This module provides access for both low-pass filtered data as well as high-pass filtered data. This minimizes the data analysis required for jolt detection and faster transitions. Moreover,  this digital MMA8452Q Triaxial accelerometer supports three embedded channels of motion detection.

• Freefall or motion detection: one channel
• Pulse detection: one channel
• Jolt detection: one channel

Meanwhile, this device is configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8451Q to monitor events and remain in a low-power mode during periods of inactivity. This IC is available in a 16-pin QFN, 3 mm x 3 mm x 1 mm package.

APPLICATIONS

• E-compass applications
• Used in Static orientation detection for portrait/landscape, up/down, left/right, back/front position identification
• Notebook, e-reader, and laptop tumble and freefall detection
• In Real-time orientation detection such as virtual reality and gaming 3D user position feedback
• Real-time activity analysis like pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup
• In Shock and vibration monitoring where mechatronic compensation, shipping and warranty usage logging  considered
• User interface (menu scrolling by orientation change, tap detection for button replacement)
