STMicroelectronics released a tiny, low-power micro-electro-mechanical (MEMS) device that provides acceleration values in all three dimensions and miniaturizes motion-sensing in portable electronic devices.
The analog-output LIS302ALK provides individual acceleration values for all three (x, y and z) axes. The sensor is housed in a 5 x 3 x 0.9 millimeter plastic package to fit in a variety of space-constrained applications.
Its compact design provides shock survivability up to 10,000 g in 0.1 millisecond (msec).
The sensor offers an output range of +/-2.0 g and monitors low-frequency vibration at low power consumption.
It uses a power-down mode to reach 1 microamp (µA) supply current. Its built-in self-test capability allows the customer to verify functioning after the sensor has been assembled on board.
The LIS302ALK uses ST Ecopack lead-free technology for compliance with the EU Restriction of the Use of Certain Hazardous Substances (RoHS) Directive.
The ST family of LIS302 MEMS motion sensors address different system needs and hardware characteristics in a range of low-g applications including free-fall detection for data-integrity protection in hard-disk drives, vibration monitoring and compensation, damage prevention, remote control and motion user interfaces in mobile and gaming devices.
They also can be used to manage power consumption of products that need to be powered on or off while or after they have been touched or moved.
