ME4058B6SG是南京微盟(MICRONE)推出的一款锂电池充电管理芯片,针对2-3节锂电池设计,具备宽输入电压范围、低静态功耗、宽温工作等特性,适合对体积、功耗及可靠性要求较高的便携式及工业应用场景。
ME4058B6SG定位于中小功率锂电池充电场景,核心价值聚焦于「适配性+可靠性+低功耗」:
ME4058B6SG的关键参数覆盖充电全流程需求,具体如下:
参数项 规格值 应用说明 芯片类型 锂电池充电管理芯片 专为2-3节锂离子电池(Li-ion)设计 输入工作电压范围 8.9V ~ 20V DC 兼容主流适配器及电源输入 最大充电电流 2A 满足中小容量锂电池快速充电需求 充电饱和电压 8.4V ± 1%(典型) 适配2节锂电池(4.2V/节)满电状态 电池节数适配 2 ~ 3节 3节应用需结合外围电路调整充电参数 工作温度范围 -40℃ ~ +85℃ 工业级宽温,适合户外及极端环境 静态电流(Iq) 9uA(典型值) 待机功耗极低,不影响电池长期存储 电池温度检测 支持NTC热敏电阻检测 过温时自动关断充电,避免电池老化/起火 封装形式 SOP-8(贴片式) 尺寸5.2mm×6.0mm×1.75mm,易集成于紧凑PCB采用恒流(CC)+恒压(CV) 双模式,符合锂电池充电规范:
内置NTC检测接口,实现三段温度监控:
当输入电压超过20V时,芯片自动关断输出,防止过压损坏电池及自身电路,提升系统抗干扰能力。
待机时静态电流仅9uA,即使设备长期处于待机状态(如应急照明、备用电源),也不会明显消耗电池电量,保障设备随时可用。
采用SOP-8贴片封装,具备三大优势:
ME4058B6SG广泛应用于以下领域:
南京微盟(MICRONE)是国内专注电源管理芯片研发的高新技术企业,拥有10余年行业经验,产品覆盖消费电子、工业控制等领域。ME4058B6SG通过以下方式保障可靠性:

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
