ME4074AM5G 产品概述

一、产品简介

ME4074AM5G 是南京微盟(MICRONE)面向单节锂离子电池充电管理的充电芯片,采用 SOT-23-5 小封装。器件工作电压范围宽(4.0V~6.5V),最大充电电流可达 800mA,恒压终止电压为 4.2V,静态电流仅 55µA,工作温度范围 -40℃~+125℃,适合体积受限且对功耗有要求的便携式电源管理场景。

二、核心规格

  • 芯片类型:充电芯片(单节锂电池管理)
  • 工作电压:4.0V ~ 6.5V
  • 最大充电电流:800mA
  • 恒压/充电饱和电压:4.2V(单节锂电池)
  • 电池类型:单节锂离子/锂聚合物
  • 工作温度:-40℃ ~ +125℃
  • 静态电流(Iq):55µA
  • 封装:SOT-23-5
  • 品牌:MICRONE(南京微盟)

三、主要特性(典型)

  • CC/CV 充电控制:满足恒流-恒压充电流程,适用于标准 4.2V 单节电芯。
  • 低待机电流:55µA 的静态电流有利于待机功耗控制,延长系统无载状态下的电池寿命。
  • 宽输入电压:4V~6.5V 可直接兼容 USB(5V)及常见适配器输入。
  • 小尺寸封装:SOT-23-5 有利于空间受限的 PCB 设计与批量化成本控制。
  • 工业级温度范围:-40℃ 至 +125℃,可用于车载、工业级与户外环境。

(注:具体保护功能、充电电流设置方式、状态指示引脚与热限流策略等,请参阅芯片数据手册以获取准确引脚定义与典型电路。)

四、典型应用场景

  • 小型移动设备:蓝牙耳机、便携式音箱、手持终端等。
  • 可穿戴与 IoT 设备:对体积与功耗敏感的智能设备。
  • 便携电源与充电盒:单节电池的充放电管理。
  • 工业与车载辅助电源:在宽温环境下的备用电池充电管理。

五、设计与应用建议

  • 热耗散考虑:若输入电压明显高于电池电压且采用较高充电电流(接近 800mA),线性充电器会产生较大功耗(P≈(VIN–VBAT)×I)。板上应留足铜箔以利散热,或在必要时选择升降压隔离方案来降低器件发热。
  • 外围元件:建议在输入端与电池端按数据手册配置适当的去耦电容与电流设定元件,保证充电稳定性与环路可靠性。
  • 保护与检测:在系统设计中增加过流、过温保护和电池状态检测电路,确保充电过程的安全与可靠。
  • 调试验证:在量产前进行充电曲线、温升与热关断测试,验证在极端工况下的稳定性。

六、采购与封装

ME4074AM5G 以 SOT-23-5 封装供应,适合自动贴装生产。采购时请确认批次与版本,并参照官方规格书获取详细引脚定义、典型应用电路和完整电气参数表。

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
