Overview

The LIS2DTW12TR is an ultra-low-power 3-axis linear accelerometer featuring an integrated high-precision temperature sensor. It offers selectable full scales of plus or minus 2g to 16g and is designed to operate in various modes, including high-performance and low-power, to optimize energy consumption for battery-operated devices.

Why Choose This Part

This sensor stands out by combining motion and temperature sensing into a single 2x2x0.7mm LGA-12 package, reducing PCB footprint and BOM cost. It achieves extreme power efficiency, drawing as little as 5 microamps at a 100Hz ODR in low-power mode while maintaining high-resolution digital output via I2C or SPI.

Applications

Industrial IoT Sensing
Utilizing the integrated temperature sensor and accelerometer for motor vibration monitoring and thermal health tracking in one package.
Gesture Recognition
Implementing tap, double-tap, and orientation detection for user interface control in portable electronics.
Motion-Activated Power Management
Using the wake-up and inactivity detection features to keep high-power system components in sleep mode until motion is detected.
Asset Tracking
Providing free-fall and impact detection for logistics and supply chain monitoring with minimal battery drain.
