STMICROELECTRONICS 3-Axis MEMS Digital Accelerometer LGA-16

The STMICROELECTRONICS LIS3DHTR is an ultra-low-power, high-performance 3-axis nano accelerometer belonging to the esteemed "nano" family of MEMS digital output motion sensors. Featuring a digital I2C/SPI serial interface standard output, this advanced sensor provides precise and reliable motion tracking data.

Designed for efficiency, the device incorporates ultra-low-power operational modes that enable advanced power saving alongside smart embedded functions. A notable feature is the self-test capability, allowing users to verify the sensor's functioning within the final application. The device can be configured to generate interrupt signals activated by two independent inertial wake-up or free-fall events, as well as by the physical position of the device itself. Furthermore, the thresholds and timing of these interrupt generators are fully programmable by the end user on the fly.

Typical Applications

This versatile accelerometer is ideal for motion-activated functions, free-fall detection, and click or double-click recognition. It is highly suitable for intelligent power saving in handheld devices, pedometers, display orientation, gaming and virtual reality input devices, impact recognition and logging, as well as vibration monitoring and compensation.
