MP2672AGD-0000-Z 产品概述

一、产品简介

MP2672AGD-0000-Z 是 MPS 推出的一款面向 2 节锂电池组的高集成 Boost 充电管理芯片,输入工作电压范围为 4.0V ~ 5.75V,输出可对 2 节串联锂电池进行最大 2A 的恒流/恒压充电(充饱和电压 8.4V)。芯片集成电芯均衡、电池温度检测、0V 唤醒充电及非易失性参数保存(NVD)功能,使用 QFN-18(2x3)紧凑封装,工作环境温度可达 -40℃ ~ +125℃,静态电流仅 31μA,支持 I2C 总线通信与配置。

二、主要功能与特性

  • 恒流/恒压(CC/CV)充电策略,支持涓流充电与充电终止;
  • 集成电芯均衡(cell balancing),提高两节电芯电压一致性与寿命;
  • 支持从 0V 电池安全唤醒并开始充电,便于深度放电后恢复;
  • 可编程充电电流,最高 2A,支持自动再充电(自动补充);
  • 电池温度检测接口(NTC),便于实现温度安全策略;
  • I2C 接口用于配置、状态查询与故障上报;NVD 用于保存关键配置信息;
  • 低静态功耗(Iq = 31μA),适合电量敏感的便携应用。

三、典型应用场景

  • 便携移动电源(从单节输入升压为 2 节输出的便携充电器);
  • 双节锂电池便携设备、手持终端、通讯基站后备电源;
  • 小型电动工具、无线设备与智能充电模块等需要体积小、管理功能完整的 2S 充电方案。

四、设计注意事项与建议

  • 输入电源能力:为支持 2A 输出充电,估算输出功率约 8.4V×2A=16.8W;以 5V 输入与 90% 效率估算,输入电流约为 3.7A,需确认输入线缆、USB 或适配器能够提供足够电流,并在 PCB 布局中考虑走线阻抗与热耗散。
  • 外部元件选择:注意电感、肖特基/同步 MOSFET、输入/输出电容和电流检测电阻的额定值与热性能。均衡电路需匹配分流能力与均衡阈值。
  • 热管理:QFN-18 带大焊盘,建议在 PCB 下方做充足的散热铜箔和过孔阵列,靠近芯片放置热敏元件以便监控。
  • I2C 与安全策略:通过 I2C 编程充电电流、终止阈值与均衡参数,系统层面应实现过温、过压、短路、失衡等保护逻辑。

五、封装与可靠性

芯片采用 QFN-18(2x3)小尺寸封装,便于空间受限产品布板。工作温度范围 -40℃~+125℃ 满足工业级应用要求,适用高温与低温环境。

六、安全与系统集成建议

建议在系统中配合独立过压/欠压保护、熔断器或 MOSFET 断电方案,并实现温度与电流极限保护。均衡功能提高电芯一致性,但系统级仍需定期检测电池健康与循环次数。充分利用 I2C 和 NVD 功能,可在 MCU 中保存并恢复关键充电参数与历史状态,提升系统鲁棒性。

总结:MP2672AGD-0000-Z 以其高集成度、低静态功耗与丰富的电池管理特性,适合体积受限且要求智能管理的 2 节锂电池充电方案。设计时重点关注输入电源能力与热管理,以确保在最大充电电流下的可靠性与安全。

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
