ME4069ASPG 产品概述

ME4069ASPG 是南京微盟(MICRONE)推出的一款开关型单节锂电池充电控制器,封装为 ESOP-8,针对便携式设备与小型电源系统提供高效、可靠的充电解决方案。芯片最大充电电流可达 1.8A,适合对充电速率有一定要求且对发热与效率敏感的应用场景。

一、主要性能参数

  • 最大充电电流:1.8A
  • 工作电压范围(输入):4.7V ~ 5.5V(兼容 USB 5V 输入)
  • 充电终止电压(饱和电压):4.2V(单节锂电)
  • 节数:1 节锂电池
  • 静态电流(Iq):1μA(低待机功耗)
  • 工作温度范围:-40℃ ~ +85℃
  • 支持电池温度检测(NTC 温度监测接口)
  • 封装:ESOP-8

二、功能与特点

  • 开关型充电结构:相较于线性充电器,开关型拓扑提供更高转换效率与更小的功耗,充电过程发热显著减小,适合高电流充电场合。
  • 低静态电流:1μA 的待机电流有利于节能型产品与长期待机设备,减少电池自耗。
  • 温度监测支持:内置或外接电池温度检测引脚,可实现充电温度范围判断与保护,提高充电安全性。
  • 宽输入电压:4.7~5.5V 的输入适配常见 USB 电源,便于在移动设备中直接使用。

三、典型应用场景

  • 便携式消费电子:蓝牙音箱、掌上游戏机、便携摄像机等需较快充电的设备。
  • 移动电源与充电坞:单节电池或小容量电源管理模块。
  • 智能家居与物联网终端:要求低待机功耗且偶尔快速充电的节点设备。
  • 便携医疗与工业便携设备:工作温度范围广,适用于严苛环境。

四、设计与使用建议

  • 外围器件选择:按厂方参考设计选配合适电感、肖特基二极管(若需要)与输入/输出电容,以保证稳压与低纹波。
  • 温度检测:建议接入合适的 NTC 热敏电阻并校准触发阈值,确保在异常温度下终止或限制充电。
  • PCB 布局:开关充电器对布局敏感,尽量缩短信号回路、合理布置电感与输入/输出电容,增强散热。
  • 保护与监控:配合系统软件实现充电状态监控、限流与安全计时,提升整体可靠性。

五、优势总结

ME4069ASPG 以其 1.8A 的充电能力、开关型高效拓扑与极低待机电流,适合对能效与充电速度有均衡要求的单节锂电应用。ESOP-8 封装利于热管理与功率布局,宽温工作范围使其能在多种环境下稳定工作。对于追求低功耗、充电快速且安全可控的便携设备设计,ME4069ASPG 是一款具有竞争力的充电控制方案。

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
