General description
The BMA020 is a triaxial, low-g acceleration sensor IC with digital output for consumer market applications. It allows measurements of acceleration in three perpendicular axes.
An evaluation circuitry converts the output of a three-channel micromechanical acceleration-sensing structure that works according to the differential capacitance principle.
Package and interface have been defined to match a multitude of hardware requirements. Since the sensor IC has small footprint and flat package it is attractive for mobile applications. The sensor IC can be programmed to optimize functionality, performance and power consumption in customer specific applications.
The BMA020 senses tilt, motion and shock vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

Typical applications
• Menu scrolling
• Tap sensing functionality
• Gaming
• Pedometer, step-counting
• Drop detection for warranty logging
• Display profile switching
• Advanced system power management for mobile applications
• Shock detection
