MP2759GQ-0000-Z 产品概述

一、产品简介

MP2759GQ-0000-Z 是 MPS 面向锂离子/锂聚合物电池充电管理的高集成充电芯片,工作电压范围宽(4V ~ 36V),支持 1 至 6 节电池组,最大充电电流可达 3A,典型充电终端电压为 4.2V。器件采用 QFN-19(3x3mm)封装,集成多种充电控制功能,适合车载、便携及工业级电源管理应用。

二、主要特点

  • 支持 1~6 节锂离子/聚合物电池充电(每节 4.2V 终止电压)
  • 宽输入电压范围:4V ~ 36V,适应多种电源环境
  • 最大充电电流:3A,可编程以适配不同电池容量
  • 低静态电流:IQ ≈ 1mA,降低系统待机损耗
  • 支持电池温度检测(NTC),实现 JEITA 类温度管理
  • 具备恒流(CC)、恒压(CV)、涓流、充电终止与自动再充电等功能
  • 欠压锁定、充电终止与热保护等多重安全机制

三、电气性能参数(概要)

  • 工作电压:4V ~ 36V
  • 最大充电电流:3A(可编程)
  • 充电饱和电压:4.2V(单节)
  • 电池节数支持:1 ~ 6 节
  • 工作温度范围:-40℃ ~ +125℃
  • 静态电流:约 1mA
  • 封装:QFN-19(3x3mm)

四、功能说明

  • 恒流/恒压充电:在预设恒流阶段对电池进行快速充电,接近设定终止电压后进入恒压阶段,控制电压为 4.2V/节。
  • 涓流充电:在电池电压较低时启动涓流以保护电池并提高进入快速充电的可靠性。
  • 充电终止与自动再充电:当充电电流降至终止阈值时停止充电;当电池电压下降到再充电阈值时自动重新开启充电。
  • 电池温度检测:支持外接 NTC,按温度范围自动调整或禁止充电,保护电池寿命与安全。
  • 欠压锁定与热保护:输入欠压或芯片过温时限制或停止充电,保障系统可靠性。

五、应用建议与布局注意事项

  • 充电电流通过外部编程电阻或电流采样电阻设定,设计时需根据电池容量与热预算合理选择(最大 3A)。
  • 大电流充电时需注意散热,建议在 PCB 下方使用大面积导热铜箔并连接裸露散热焊盘(EP),确保芯片和周边元件热降额。
  • 电池温度检测要靠近电池放置 NTC,确保温度读数准确,避免误动作。
  • 输入端需加入合适的输入滤波与反极性保护元件,输出(电池侧)应配置防反接保护与必要的滤波电容,提升系统稳定性。
  • 若用于多节串联电池系统,应配合电池组管理或均衡电路保证各节一致性与安全。

六、封装与环境指标

  • 封装:QFN-19(3x3mm),利于小型化设计与较好散热
  • 工作温度:-40℃ 至 +125℃,适应工业级应用场景
  • 品牌:MPS(Monolithic Power Systems),适合要求高可靠性的产品设计

七、典型应用场景

  • 车载电源与车载便携设备充电管理
  • 便携式消费电子(平板、笔记本延长电源)
  • 工业便携工具、电池组维护与管理系统
  • UPS、备用电源及多节电池包充电管理

MP2759GQ-0000-Z 在宽输入、高集成与多重保护设计之间取得平衡,适合对充电安全、效率与体积有严格要求的产品。设计时请结合电池厂商建议与系统热设计进行验证,以获得最佳可靠性与寿命表现。

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
