LIS2DHTR Accelerometer by STMicroelectronics

The LIS2DHTR is a versatile, low-power, high-performance 3-axis "nano" accelerometer with digital I2C/SPI serial interfaces from STMicroelectronics. This MEMS sensor features ultra-low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions. The LIS2DHTR is specifically designed for mobile applications and consumer electronics where extended battery life is a critical requirement.

The device has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. Moreover, the LIS2DHTR includes high-resolution modes and an embedded FIFO (First In, First Out) buffer allowing the user to store data for host processor offloading, thereby reducing power consumption.

The LIS2DHTR's robust design and high shock survivability (up to 5000g) make it an ideal choice for a wide array of applications, including motion detection, impact recognition and logging, vibration monitoring and compensation, and intelligent power-saving for handheld devices. Its small form factor and low power consumption, combined with the feature-rich capabilities, provide a highly reliable and sophisticated accelerometer solution for advanced motion-based applications.

Key features of the LIS2DHTR include:

• Analog supply voltage range from 1.71 V to 3.6 V
• Independent IO supply (1.8 V)
• Low power consumption down to 2 μA in low-power mode
• ±2g/±4g/±8g/±16g dynamically selectable full scales
• I2C/SPI digital output interface
• 16-bit data output
• Multiple operating modes for optimal power saving
• Embedded FIFO for data storage and dynamic stream rate change
• High shock survivability

The LIS2DHTR 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. This makes it a reliable choice for both industrial and consumer applications where efficiency and longevity are paramount.
