LIS2MDL:
ultra-low-power, high-performance 3D magnetometer
Introduction
This document is intended to provide usage information and application hints related to ST’s
LIS2MDL motion sensor.
The LIS2MDL is a 3D digital magnetometer system-in-package with a digital I²C and 3-wire
SPI serial interface standard output, performing at 200 μA in high-resolution mode and no
more than 50 μA in low-power mode (at 20 Hz output data rate). Thanks to the ultra-low
noise performance of the magnetometer, the device combines always-on low-power
features with superior sensing precision for an optimal motion experience for the consumer.
The device has a magnetic field dynamic range of ±50 gauss.
The LIS2MDL can be configured to generate an interrupt signal for magnetic field detection
and to automatically compensate for hard-iron offsets provided from the higher application
layer.
ST software support available for the LIS2MDL includes drivers, a tilt-compensated
electronic compass, dynamic magnetometer calibration, and 6-axis or 9-axis sensor fusion.
