LSM6DSV16BX Integrated Circuits ICsf With UI Sensor For Hearing Aids

The LSM6DSV16BX boasts a wealth of features, compact packaging, and efficient data processing capabilities, making it an ideal choice for a wide range of applications including wearable devices, TWS (True Wireless Stereo) earphones, hearing aids, AR/VR headsets, and smart glasses.

Here's a detailed translation of its key parameters into English:

Basic Parameters

• Packaging: System-in-Package (SiP) measuring 2.5 mm x 3.0 mm x 0.71 mm, ensuring a compact footprint.

Functional Characteristics

• Integrated Sensors: Combines a 3D digital accelerometer and a 3D digital gyroscope, processing acceleration, angular velocity, and Qvar sensing data on three independent channels with dedicated configuration, processing, and filtering capabilities.
• UI Sensor: Offers a low-power, always-on experience with a working current of just 0.6 mA in high-performance mode, enhancing the motion experience for wearable and TWS applications.
• Audio Accelerometer: Enables bone conduction for high-precision audio transmission and detection.
• Qvar Sensor: Embedded Qvar (charge variation detection) functionality allows for presence and motion detection through external electrodes, suitable for in-ear detection scenarios.

Data Processing & Performance

• Programmable Finite State Machine (FSM): Handles accelerometer, gyroscope, and Qvar sensor data processing at rates up to 960 Hz.
• Machine Learning Core: Features output functions and filters for AI applications, supporting edge processing with AI algorithms.
• Intelligent FIFO: Up to 4.5 KB of FIFO (First-In, First-Out) buffer helps reduce system power consumption and improve data processing efficiency.
• Low Power Consumption: Achieves a power consumption of 0.95 mA in combined high-performance mode, with low-power options for both the accelerometer and gyroscope enabling an "always-on" experience.

Range & Accuracy

• Accelerometer Range: ±2/±4/±8/±16 g.
• Gyroscope Range: ±125/±250/±500/±1000/±2000/±4000 dps.

Interfaces & Power

• Communication Interfaces: Supports SPI, I²C, and MIPI I3C® v1.1 serial interfaces, enabling data synchronization with the host processor.
• Supply Voltage: Analog supply voltage range from 1.71 V to 3.6 V, with an independent IO supply (extended range: 1.08 V - 3.6 V).

Additional Features

• Embedded Temperature Sensor: Provides temperature monitoring capabilities.
• Embedded Analog Hub: Capable of connecting external analog inputs and converting them into digital signals for processing.
• Compliance: Compliant with ECOPACK and RoHS standards, ensuring environmental friendliness and reliability.
