LIS2DTW12TR 3轴MEMS加速度计产品概述

LIS2DTW12TR是意法半导体(ST)推出的工业级低功耗3轴MEMS加速度计模块,集成温度传感器,以宽量程、高分辨率、超小待机功耗为核心特性,适配电池供电、空间受限及工业环境等多类应用场景。

一、产品定位与核心功能

该产品定位于多功能集成型MEMS传感器,同时实现3轴加速度检测与温度感知,无需额外添加温度传感器即可完成基础环境监测,简化系统设计。其核心功能覆盖:

  • 3轴(X/Y/Z)线性加速度精准测量;
  • 片上温度传感器实时监测环境温度(可用于加速度补偿,提升精度);
  • 低功耗模式下长期待机,适配电池供电设备。

二、关键性能参数详解

1. 加速度计核心参数

  • 量程范围:最大±16g,覆盖常规运动(±2g~±8g)及高冲击/振动场景(如工业机械、汽车辅助系统);
  • 输出分辨率:16bit,计算得最小分辨率约0.488mg/LSB(±16g量程下),可精准捕捉微小加速度变化(如人体微小动作、设备细微振动);
  • 轴向:X、Y、Z三轴正交,满足空间姿态检测需求。

2. 功耗与电压特性

  • 待机电流:仅50nA,为同类产品中极低水平,显著延长电池供电设备的待机时间(如物联网节点、可穿戴设备可待机数月至数年);
  • 工作电压:1.62V~3.6V,兼容主流MCU的3.3V供电及低电压电池(如纽扣电池、锂聚合物电池)。

3. 环境适应性

  • 工作温度:-40℃~+85℃,符合工业级温度标准,可稳定工作于户外、工厂车间等极端环境;
  • 可靠性:经ST严格可靠性测试,适配工业应用的振动、湿度等复杂工况。

三、接口与封装设计

1. 灵活接口

支持I2C(最高1MHz)与SPI(最高10MHz)双数字接口,可根据MCU资源灵活选择:

  • I2C适合多传感器并联(需地址配置),节省引脚;
  • SPI适合高速数据传输,满足实时监测需求(如运动捕捉、振动分析)。

2. 小型化封装

采用12-WFLGA(晶圆级芯片尺寸封装),尺寸极小(典型1.6mm×1.6mm×0.7mm),无引脚设计减少占位空间,适配:

  • 可穿戴设备(智能手环、智能手表);
  • 小型物联网节点(智能传感器、资产追踪器);
  • 紧凑型工业设备(小型电机监测模块)。

四、典型应用场景

结合核心参数,LIS2DTW12TR可广泛应用于以下领域:

  1. 工业设备监测:检测电机、泵、风机的振动异常,提前预警故障(宽量程覆盖设备启动/停止的高冲击,低功耗适配无线监测节点);
  2. 可穿戴与健康监测:智能手环的步数、睡眠、摔倒检测(16bit分辨率精准捕捉人体动作,50nA待机延长续航);
  3. 物联网(IoT)节点:智能垃圾桶倾斜检测、智能花盆湿度联动(低功耗适配纽扣电池供电,宽温适应户外环境);
  4. 汽车电子辅助:汽车姿态检测、碰撞预警(-40~85℃符合车载环境,宽量程覆盖颠簸、急刹场景);
  5. 消费电子:智能手机/平板的屏幕自动旋转、游戏手柄姿态控制(小封装适配设备内部空间)。

五、核心优势总结

  1. 超低碳功耗:50nA待机电流,解决电池供电设备的续航痛点;
  2. 宽量程+高分辨率:±16g量程覆盖多场景,16bit分辨率保证精准度;
  3. 集成化设计:片上温度传感器简化系统,无需额外元件;
  4. 工业级可靠性:宽温范围、高抗干扰性,适配 harsh环境;
  5. 灵活兼容性:双接口、宽电压、小封装,适配各类MCU与设备形态。

LIS2DTW12TR凭借其低功耗、宽量程、集成化等特性,成为工业监测、可穿戴、物联网等领域的高性价比MEMS传感器选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
