ME4084BN8BG 产品概述

ME4084BN8BG 是 MICRONE(南京微盟)推出的一款针对单节锂电池的集成充电管理芯片,封装为 DFN-8-EP(2×2)。器件集成高精度充电控制与多重保护功能,适用于便携设备、智能硬件与电池供电模块等需要安全、稳定充电管理的场景。

一、产品简介

ME4084BN8BG 为单节锂离子/锂聚合物电池设计的充电芯片,支持外部电源工作电压范围 4.7V~6.5V,最大可提供 800mA 的充电电流。芯片静态工作电流(Iq)为 100μA,在电源断开或待机时可降低系统待机功耗。工作环境温度范围为 -40℃~+85℃,满足工业级温度要求。

二、主要性能参数

  • 最大充电电流:800mA
  • 充电饱和电压(终止电压):4.2V(适用于标准锂电池)
  • 工作电压范围:4.7V~6.5V(外部输入)
  • 静态电流(Iq):100μA
  • 工作温度:-40℃~+85℃
  • 电池节数:1 节锂电池
  • 支持电池温度检测(NTC 接入)

三、功能与保护

ME4084BN8BG 集成恒流-恒压(CC/CV)充电算法,具备精准的终止检测与充电限流功能。芯片提供一系列保护机制,包括过温保护(对充电温度异常进行限流或关断)、过压/欠压保护、充电超时保护与短路保护。同时支持外部温度检测接口,方便实现充电温度依赖的充电策略,提高电池安全性与寿命。

四、封装与热管理

器件采用 DFN-8-EP(2×2)小型裸露焊盘封装,便于高密度 PCB 布局。由于充电过程中功耗集中在芯片与 MOSFET/外置元件上,建议在 PCB 设计中使用大面积散热地或放置于内层散热铜箔,以降低芯片结温并保证长期可靠性。考虑到最大 800mA 充电电流,应评估功率耗散与外部电感、电阻的选择。

五、典型应用场景

  • 便携式电子设备(蓝牙耳机、智能手表扩展底座)
  • 物联网终端、传感器节点的电池供电管理
  • 小型充电宝、便携充电模块
  • 工业无线模块及电池备份电路

六、设计建议与注意事项

  • 依据电池容量与充电要求设置合理的充电电流(不超过 800mA)。
  • 使用合适的充电电阻、MOS 管和输入保护元件,确保在异常输入下系统安全。
  • 必须接入电池温度检测(NTC),并在温度异常时采取限流或关断策略。
  • 在 PCB 布局上优先考虑散热路径,注意电源引脚与大电流回路的走线宽度。
  • 开发与验证时进行充电循环测试、温升测试与异常工况仿真,确保可靠性。

ME4084BN8BG 提供了针对单节锂电池的高集成度充电解决方案,适合对体积、成本和可靠性有较高要求的应用场合。若需完整 datasheet 与参考设计,建议联系 MICRONE(南京微盟)获取详细资料与评估板。

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
