MAX3225EEUP+T 产品概述

一、产品简介

MAX3225EEUP+T 是 ADI(原 Maxim/Linear)系列的低功耗 RS-232 收发器,集成内部电荷泵并具备 AutoShutdown Plus 功能。器件提供 2 个驱动器与 2 个接收器,支持高达 1 Mbps 的串口速率,工作电压范围宽(3.0 V~5.5 V),适用于对功耗、体积和抗干扰有较高要求的通信系统。

二、主要特性

  • 双驱动器、双接收器:满足常见串口点对点或多通道需求。
  • 数据速率:最高可达 1 Mbps,适合高速 RS-232 应用。
  • 宽电源范围:3.0 V~5.5 V,兼容 3.3 V 与 5 V 系统。
  • 内置电荷泵:无需外部 ±12 V 电源即可产生 RS-232 所需电平(通常配合小型外部电容使用)。
  • AutoShutdown Plus:在总线空闲或无通信时自动进入超低功耗模式,静态电流低至约 1 µA。
  • 强化静电保护:对外接口 ESD 防护等级可达 ±15 kV(IEC 61000-4-2 标准),提高系统可靠性。
  • 宽温区:工作温度 -40 ℃~+85 ℃,适合工业级应用。
  • 驱动能力:具有良好峰值输出能力(典型峰值可达 1 A),保障短路或负载瞬态下的稳定性。
  • 封装:TSSOP-20,节省 PCB 面积,便于自动贴装。

三、电气与机械参数(要点)

  • 静态电流(关断/待机):≈1 µA(典型),适合电池供电设备。
  • 供电与接口:单电源工作,TTL/CMOS 侧直接接口;RS-232 侧电平由内部电荷泵生成。
  • 封装与焊接:TSSOP-20,推荐按厂家参考封装图与焊盘设计。

四、典型应用场景

  • 工业自动化与现场控制器:长线 RS-232 通信、抗干扰要求高。
  • 便携式与电池供电设备:低静态电流与宽电压范围满足续航需求。
  • POS 机、条码扫码器、票据打印机等外围设备。
  • 测试与测量设备、GPS 接收器、嵌入式调试接口。

五、设计与使用建议

  • 虽然器件集成电荷泵,但建议按数据手册推荐配置外部电容以保证电荷泵稳定与输出电平质量。
  • 为发挥 ±15 kV 的 ESD 防护效果,布局时注意将敏感走线与接地平面合理安排,且器件引脚在生产和维护环节仍应遵循静电防护规范。
  • 在需要高可靠性的工业环境,应进行整体电源滤波与浪涌抑制设计,避免长期高压尖峰影响器件寿命。
  • 安装封装时参考 TSSOP-20 的热沉与焊盘建议,保证焊接可靠性与散热。

六、优势总结

MAX3225EEUP+T 将宽电压、低功耗、内置电荷泵与强 ESD 保护集合于紧凑的 TSSOP-20 封装,适合要求可靠通信、低功耗待机和工业温度范围的设计。其 AutoShutdown Plus 功能和微安级静态电流使其在电池供电与节能型系统中具有明显优势,是替换传统大功耗 RS-232 收发器的理想选择。

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
