DESCRIPCIÓN

The LSM6DS3TR-C is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 0.90 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer.
The LSM6DS3TR-C supports main OS requirements, offering real, virtual and batch sensors with 4 kbyte for dynamic data batching.
ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes.
The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.
The LSM6DS3TR-C has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±250/±500/±1000/±2000 dps.
High robustness to mechanical shock makes the LSM6DS3TR-C the preferred choice of system designers for the creation and manufacturing of reliable products.
The LSM6DS3TR-C is available in a plastic land grid array (LGA) package.

OVERVIEW

The LSM6DS3TR-C is a system-in-package featuring a high-performance 3-axis digital accelerometer and 3-axis digital gyroscope.
The integrated power-efficient modes are able to reduce the power consumption down to 0.90 mA in high-performance mode, combining always-on low-power features with superior sensing precision for an optimal motion experience for the consumer thanks to ultra-low noise performance for both the gyroscope and accelerometer.
The LSM6DS3TR-C offers hardware flexibility to connect the pins with different mode connections to external sensors in order to expand functionalities such as adding a sensor hub, etc.
Up to 4 kbyte of FIFO with dynamic allocation of accelerometer and gyroscope data allows overall power saving of the system.
Like the entire portfolio of MEMS sensor modules, the LSM6DS3TR-C leverages the robust and mature in-house manufacturing processes already used for the production of micromachined accelerometers and gyroscopes. The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.
The LSM6DS3TR-C is available in a small plastic land grid array (LGA) package of 2.5 x 3.0 x 0.83 mm to address ultra-compact solutions.

 

TILT DETECTION

The tilt function helps to detect activity change and has been implemented in hardware using only the accelerometer to achieve both the targets of ultra-low power consumption and robustness during the short duration of dynamic accelerations.
It is based on a trigger of an event each time the device’s tilt changes. For a more customized user experience, in the LSM6DS3TR-C the tilt function is configurable through:
1.a programmable average window
2.a programmable average threshold
The tilt function can be used with different scenarios, for example:
a) Triggers when phone is in a front pants pocket and the user goes from sitting to standing or standing to sitting;
b) Doesn’t trigger when phone is in a front pants pocket and the user is walking, running or going upstairs.
