Accelerometer with high-accuracy temperature sensor
28 August 2019, Analogue, Mixed Signal, LSI
The STMicroelectronics LIS2DTW12 combines a MEMS 3-axis accelerometer and a temperature sensor on a single die for use in space-constrained and battery-sensitive detectors such as shipping trackers, wearables and IoT endpoints. The sensing accuracy of 0,8°C offers precision comparable with standalone standard temperature sensors.
In addition to enhanced temperature compensation, the flexibility provided by 65 different user modes enables developers to optimise power consumption and noise to meet application-specific requirements. The chip has a user-selectable full-scale range up to ±16 G and measures acceleration with output data rates from 1,6 Hz to 1600 Hz.
With a package height of just 0,7 mm, the LIS2DTW12 allows extra battery capacity for longer runtimes. Power-saving features include a 50 nA power-down mode, multiple operating modes down to less than 1 µA, a dedicated internal engine for processing accelerometer signals, and a large 32-level FIFO to reduce intervention from the main controller.
The device provides 16-bit accelerometer data and 12-bit temperature data through a high-speed I2C/SPI port, and allows single data conversion on demand. The motion engine performs free-fall and wakeup detection, single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection, and 6D/4D orientation. ST’s advanced self-test capability is also built-in to verify the sensor is functioning correctly.
