BMA253-HXY 产品概述

一、产品简介

BMA253-HXY 是华轩阳电子(HXY MOSFET)提供的一款三轴加速度计,测量轴向为 X、Y、Z,采用 12-bit 输出,支持 I2C 与 SPI 两种数字通信接口。器件工作电压范围宽(1.71V ~ 3.6V),工作温度覆盖行业常用的 -40℃ 至 +85℃,适合电池供电与工业级应用场景。

二、主要技术指标

  • 传感器类型:加速度计(3 轴:X、Y、Z)
  • 量程(最大):±16 g
  • 输出分辨率:12 bit(4096 量化级)——在 ±16 g 量程下,量化步长约 32g/4096 ≈ 7.8 mg/LSB
  • 接口类型:I2C、SPI(双总线支持,选择灵活)
  • 工作电压:1.71 V 至 3.6 V(兼容 1.8V 与 3.3V 系统)
  • 待机电流:500 nA(低功耗待机,有利于续航设计)
  • 工作温度:-40℃ ~ +85℃
  • 封装:LGA-12 (2 x 2 mm)

三、功能特点与优势

  • 多量程支持与高量化精度:12-bit 分辨率在 ±16g 量程下可满足一般运动检测、姿态识别和振动分析的精度需求。
  • 低功耗:待机电流仅 500 nA,适合可穿戴与电池供电产品的能耗优化。
  • 双接口设计:I2C 便于多设备总线连接,SPI 提供更高带宽与确定时序,便于实时数据采集。
  • 宽电压与宽温度:适配多种平台与恶劣环境下的可靠工作。

四、典型应用场景

  • 智能手机、可穿戴设备与手环的运动检测与计步
  • 电源管理与设备唤醒(低功耗手势或移动触发)
  • 游戏与虚拟现实的姿态感知
  • 工业振动监测、设备健康检测与倾斜检测
  • 物联网终端的入侵/移动检测

五、硬件接口与使用建议

  • 电源滤波:建议在 VDD 近旁放置 0.1 µF 陶瓷旁路电容,减小电源噪声对测量精度的影响。
  • I2C 使用:为 SDA、SCL 添加与 VDD 相连的上拉电阻(典型 2.2kΩ 至 10kΩ,依总线速率与主控配置)。
  • SPI 使用:保证 CS、SCK、MOSI、MISO 的走线完整性,避免长线引入噪声。
  • PCB 布局:器件应尽量靠近测量目标中心或参考重心放置,避免靠近高频开关器件与热源;LGA 封装需遵循厂家焊盘与回流工艺规范。
  • 电磁与机械隔离:在振动敏感应用中,确保安装结构良好以减小机械耦合误差;避免在器件下方直接敷铜大面积,以减少热应力不均。

六、封装与可靠性

BMA253-HXY 采用 LGA-12(2x2 mm)小尺寸封装,适用于空间受限的移动设备与模块化设计。器件的工作温度范围与低待机电流使其在消费电子与轻工业环境中具备良好的可靠性表现。具体焊接、封装尺寸与可靠性测试参数请参考华轩阳电子提供的规格书与焊接指南。

七、选型与订购建议

选型时确认目标系统的供电电压、通信总线类型与量程需求;若主要关注低功耗休眠与电池寿命,BMA253-HXY 的 500 nA 待机特性为优势。关于样片、量产与技术支持,建议联系华轩阳电子或授权分销渠道获取最新 Datasheet、评估板与应用笔记,以便完成可靠设计与认证。

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
