DS8500-JND+T&R 产品概述

一、产品简介

DS8500-JND+T&R 为 ADI/Linear 系列的 QFN-20-EP (5×5 mm) 封装器件,提供带底板(EP)的紧凑尺寸与良好散热性能。器件采用 UART 串行接口,支持低速数据传输(典型 1.2 kbps),工作电压范围 2.7 V 至 3.6 V,工作温度范围 -40℃ 至 +85℃,适合工业级和商用级嵌入式系统。

二、关键参数

  • 接口类型:UART(异步串行通信)
  • 数据速率:1.2 kbps(典型/推荐速率,兼容低速通信需求)
  • 工作电压:2.7 V ~ 3.6 V
  • 工作温度:-40℃ ~ +85℃
  • 封装:QFN-20-EP (5×5 mm)
  • 包装方式:T&R(卷带,适合自动贴片生产)
  • 品牌:ADI(Analog Devices / Linear Technology)

三、主要特性与优势

  • 低功耗设计,适合电池供电或能耗受限应用。
  • 宽电源电压范围,易于与 3.3 V 微控制器和外围器件直接接口。
  • 工业温度等级,保证在严苛环境下稳定工作。
  • QFN-20-EP 小尺寸、高密度,利于空间受限的 PCB 布局,同时底板增强热性能与焊接可靠性。
  • T&R 包装适合大批量 SMT 生产。

四、典型应用场景

  • 工业控制与传感节点(远程数据采集、参数配置)
  • 智能表计和遥测终端(低速串行链路)
  • 嵌入式通信模块(设备间配置与故障日志传输)
  • 电池供电的便携设备与无线子系统控制信道

五、设计与应用建议

  • 电源旁路:在器件 VCC 近端布局 0.1 μF 陶瓷旁路电容,并建议配合 1~10 μF 稳定电容,降低电源噪声。
  • UART 线路保护:对外部长线或易受干扰环境,建议使用小体积 TVS 或限流电阻、共模滤波器以提高抗干扰和 ESD 保护。
  • 电压兼容:若主控侧为非 3.3 V 逻辑(如 1.8 V 或 5 V),需加电平转换电路。
  • PCB 布局:QFN 底板应连到 GND 平面,建议在底板下方留通孔或热通孔优化散热;焊膏打印覆盖率可控制在 50%~70%,避免焊膏过多导致虚焊或翘曲。
  • 焊接工艺:遵循器件制造商推荐的回流温度曲线,控制最大回流温度和时间,确保封装与底板焊接可靠。

六、测试与验证要点

  • 供电稳定性测试:测量上电/掉电过程中器件行为,验证在 2.7 V 边界条件下功能完整性。
  • UART 通信验证:在目标波特率(1.2 kbps)及不同帧格式下测试链路稳定性和误码率。
  • 环境应力测试:做温度循环与高低温功能确认,验证 -40℃ 至 +85℃ 下性能一致性。
  • 焊接可靠性:进行热循环、振动测试,检验 QFN-EP 焊点与底板焊接质量。

七、采购与封装信息

  • 封装型号:QFN-20-EP (5×5 mm),底部带热焊盘(EP)。
  • 包装方式:T&R(卷带/卷盘),适合 SMT 线上自动化贴装与回流焊接。
  • 合规性:通常符合 RoHS 要求(具体请以供应商出具的合格证为准)。

备注:以上为基于提供参数的产品概述与设计建议。若需详细引脚分配、时序、典型电路图和精确回流曲线,请参考厂商原始 datasheet 与应用笔记,或提供具体使用场景以便给出更细化的硬件实现方案。

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
