ME4064AM5G-N 产品概述

一、概述

ME4064AM5G-N 是南京微盟(MICRONE)推出的一款面向单节锂离子电池的线性充电管理芯片。器件采用 SOT-23-5 小封装,适用于空间受限的便携式设备,提供最高 800mA 的恒流充电能力,采用典型的恒流-恒压(CC/CV)充电策略,充电终止电压为 4.20V。器件静态电流低(Iq = 55µA),在电池待机或断电状态下对系统待机耗电影响小,适合对功耗敏感的移动与物联网应用。

二、主要参数

  • 型号:ME4064AM5G-N
  • 品牌:MICRONE(南京微盟)
  • 电池类型:单节锂离子电池(1S Li-ion)
  • 最大充电电流:800 mA(可通过外部电阻设定)
  • 工作电压(输入):4.0 V ~ 8.0 V
  • 充电饱和/终止电压:4.20 V
  • 静态电流(Iq):55 µA
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOT-23-5

三、功能特点

  • 支持 CC/CV 充电模式,适配标准 1 节锂电池充电曲线;
  • 最高 800mA 充电能力,满足中等功率便携设备快速充电需求;
  • 低静态电流(55µA),降低无人使用时的电池自放电影响;
  • 宽输入电压范围(4~8V),兼容 USB、适配器或电源管理模块等多种供电来源;
  • 紧凑 SOT-23-5 封装,利于小型化 PCB 布局与成本控制;
  • 适应宽温范围(-40~85℃),可用于工业级与消费级环境。

(注:具体保护机制如温度调节、充电终止判定、状态指示等请参阅原厂资料以获取详细功能列表与参数说明。)

四、典型应用场景

  • 便携式消费电子:蓝牙耳机、随身听、便携音箱;
  • 可穿戴与健康设备:智能手环、便携医疗检测仪;
  • 物联网终端与传感器节点:低功耗无线传感器、远程数据采集设备;
  • 小型手持工具与测量仪表:数码相机、便携式测量仪等。

五、设计建议与注意事项

  • 输入电压须稳定在 4~8V 范围内;如使用 USB 电源,推荐加入合适的滤波与浪涌抑制元件;
  • 充电电流由外部电阻或芯片内部设定引脚确定;高达 800mA 时需关注 SOT-23-5 封装的功耗与热耗散,建议在 PCB 上拓展散热铜箔以降低结温;
  • 在电池接入前,可考虑预充电(涓流)策略以保护深度放电电池;充电终止与电流阈值应根据电池厂商建议设定以延长电池寿命;
  • 布局上应将输入与地端的去耦电容靠近芯片引脚放置,最小化回路面积以减小噪声与干扰;
  • 产品投入量产前,建议做完整的充放电循环测试、热特性评估与安全验证(包括过压、短路、极性保护等)。

六、封装与参考资料

ME4064AM5G-N 提供 SOT-23-5 封装,便于自动贴片与低成本生产。为保证设计正确性与可靠性,请在最终设计中参照厂家完整数据手册获取管脚定义、典型应用电路、详细电气特性曲线及质量认证信息。如需更深层次的电路示例、热设计或针对特定电池型号的参数建议,可提供具体应用场景,我可协助给出更贴合的设计方案。

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
