H3LIS331DL Low-Power, High-g, Full-Scale, 3-Axis Digital Accelerometer


Industry-unique sensors from STMicroelectronics enable high-shock detection in space- and power-constrained applications

ST's H3LIS331D is the world's first motion sensor that measures very high accelerations along all three axes at ultra-low current consumption. This accelerometer addresses the need for precise shock detection, up to 400 g² in space- and power-constrained applications, from car black boxes to medical monitoring devices and sports equipment.

Whereas existing high-g shock-detection solutions are mostly based on single- or dual-axis, power-hungry, "airbag-type" sensors, ST's new high-g accelerometers deliver both the three-dimensional precision and ultra-low current consumption optimized for battery-operated applications, opening new possibilities for portable medical instrumentation and concussion monitoring in high-impact sports.

The H3LIS331DL belongs to the "nano" family with digital I²C/SPI serial interface standard output. The device features ultra-low-power operational modes that allow advanced power saving and smart sleep-to-wake functions. It has dynamically user-selectable full scales of ±100 g/±200 g/±400 g and is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz. It is available in a small, thin, plastic, land-grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40°C to +85°C.
