ME4056ASPG-N 产品概述

一、产品简介

ME4056ASPG-N 是南京微盟(MICRONE)推出的一款单节锂电池充电管理芯片,封装为 ESOP-8。芯片支持典型的恒流/恒压(CC/CV)充电策略,最高可提供 900mA 的充电电流,充电饱和电压为 4.2V。工作电压范围为 4V~7V,工作温度范围为 -40℃~+85℃,静态电流仅 55µA,适合对功耗敏感的便携式电源管理应用。

二、主要特点

  • 支持单节锂离子电池(1S)充电,充电电压 4.2V(饱和电压)
  • 最大充电电流 900mA,适合中小容量电池快速充电
  • 工作电压 4V~7V,兼容常见 USB 及小电压适配器输入
  • 低静态电流 Iq = 55µA,有利于待机功耗优化
  • 支持电池温度检测(NTC),便于实现充电安全策略
  • 工作温度范围宽(-40℃~+85℃),适合工业级及消费类产品
  • 封装:ESOP-8,利于散热与并板生产

三、功能与安全特性(概述)

ME4056ASPG-N 实现恒流-恒压充电曲线,并提供电池温度检测接口以支持热敏安全管理。芯片设计考虑到电池与系统的安全与可靠性,通常可与过压、过流、过温等保护电路配合使用,以满足不同系统的安全需求。具体保护细节与门限值建议参考官方数据手册。

四、典型应用场景

  • 便携式消费电子:蓝牙音箱、便携播放器、数码相机等
  • 智能穿戴与健康监测设备(需注意充电电流匹配)
  • 物联网终端、手持检测仪器与便携式工业设备
  • 小型电源模块、备用电源与轻量级移动电源解决方案

五、设计建议与注意事项

  • 热设计:在接近 900mA 充电电流并且输入电压较高(接近 7V)时,芯片的功耗与发热显著,建议在 PCB 设计中提高铜箔散热面积,必要时加装散热基板或外壳散热结构。
  • 输入与功率损耗:芯片温升与功率损耗由 (VIN - VBAT) × ICHARGE 决定,尽量选择合适的输入电压以降低器件功耗。
  • 温度检测:将 NTC 温度检测元件靠近电池且放置在能真实反映电池温度的位置,确保充电过程的安全策略准确。
  • 设定充电电流:常通过外部电阻设定充电电流(PROG 类引脚),请根据电池厂家推荐的充电电流和热管理能力进行配置。
  • 引脚连接与滤波:建议在 VIN、BAT 和 GND 之间配置适当旁路电容和布线,以保证稳定性与 EMI 性能。具体引脚功能与典型连接电路请参阅器件手册。

六、封装与资料获取

ME4056ASPG-N 提供 ESOP-8 封装,便于散热与自动贴装。常见引脚包括电源输入(VIN)、充电输出(BAT)、接地(GND)、温度检测(TEMP)、设定电流与状态指示等。详细引脚排列、电气特性和典型应用电路请参考 MICRONE 正式资料与数据手册。

总结:ME4056ASPG-N 以其 900mA 的充电能力、低静态电流与宽工作温度范围,适合对功耗和可靠性有较高要求的单节锂电池充电场合。在高电流与高输入电压条件下应重视热管理与PCB布局,以发挥器件最佳性能与可靠性。

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
