The single-package approach protects a robust three-axis MEMS sensor and a CMOS interface chip that provides tilting and motion information, independent of the device’s orientation, thanks to the three-axis sensing capabilities.
The LIS344AL estimates acceleration values at a very low noise level with minimized power consumption, which is especially critical in battery-operated portable systems. The new accelerometer is housed in an inexpensive 4 x 4 x 1.5mm plastic package to fit in a variety of space-constrained applications and its ultra-compact, robust design provides shock survivability up to 10,000g.
ST’s new accelerometer offers a full-scale output range of ±3.5g. The built-in self-test facility allows the user to verify both the mechanical and electrical parts of the device. The accelerometer uses ST’s ECOPACK lead-free technology for RoHS-compliance (the EU’s Restriction on Use of Hazardous Substances Directive).
The LIS344AL addresses a wide range of applications including data-integrity protection; user interface; anti-theft system; remote device control; intelligent motion-based power management; sport and health monitoring devices.
