ME4057DSPG-N 产品概述
一、产品简介
ME4057DSPG-N 是南京微盟（MICRONE）推出的一款单节锂电池充电管理芯片，针对便携式电子设备提供高效、可靠的充电解决方案。芯片工作电压范围宽（4V～9V），最高充电电流可达 1A，充电终止电压 4.35V，适用于需要较高充电终点电压的锂电池体系。
二、主要规格
- 芯片类型：充电管理芯片
- 输入工作电压：4V ～ 9V
- 最大充电电流：1A
- 充电饱和（终止）电压：4.35V（单节）
- 电池类型：单节锂电池（Li-ion / Li-poly）
- 工作温度范围：-40℃ ～ +85℃
- 电池温度检测：支持（可接热敏电阻/温度检测接口）
- 静态电流（Iq）：55 μA（低静态电流，有助于降低系统待机耗电）
- 封装：ESOP-8
三、功能与特点
- 支持典型的恒流-恒压（CC/CV）充电流程，充电终止电压为 4.35V，适配高压锂电化学体系以提升能量密度。
- 宽输入电压范围（4V～9V），兼容多种充电电源（USB、适配器等）。
- 低静态电流（55 μA），在无充电或待机条件下对电池消耗小，适用于对待机功耗敏感的便携设备。
- 支持电池温度检测功能，可外接热敏电阻（NTC）实现温度保护与充电控制，提升安全性与电池寿命。
- ESOP-8 封装，便于表面贴装加工，散热和布线处理相对方便。
四、典型应用
- 小型便携设备：蓝牙音箱、移动电源、便携仪器、手持设备等；
- 智能穿戴与物联网终端：对功耗和体积敏感的应用；
- 其他单节锂电池供电的消费电子与工业设备。
五、设计与使用建议
- 推荐在芯片输入和电池端分别配置合适的去耦电容（如：输入 10 μF100 μF、输出 10 μF100 μF，具体见器件资料），确保电源稳定与滤波。
- 若需精确设定充电电流，请参考器件资料确认是否需要外接电流检测元件（电阻）或编程电阻；高电流迹线请做宽铜且尽量缩短。
- 电池温度检测元件（NTC）应靠近电池实际位置布置，以反映真实温度；合理设置温度检测阈值，避免在极端温度下充电。
- 封装散热：ESOP-8 封装下在 PCB 布局时建议采用充足的铜箔面积、必要时增加过孔导通至背面散热层，保证长期 1A 充电时的热稳定性。
- 系统级安全：建议配合电池保护电路（过充、过放、过流、短路保护）与热保护策略，提升整机安全性和可靠性。
六、选型与采购提示
ME4057DSPG-N 适合寻求单节锂电池、1A 等级充电管理方案的设计者。选型时请结合电池化学特性（是否允许 4.35V 终止电压）、系统热设计与待机功耗要求，并参照官方资料（Datasheet）获取引脚定义、典型外接电路与详细电气参数，以完成稳健设计与验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
