LP4060B5F 产品概述

一、概述

LP4060B5F 是 LOWPOWER(微源半导体)推出的一款针对单节锂离子电池的充电管理芯片,采用 SOT-23-5 封装,适用于空间受限的便携式设备。芯片支持 3.9V6V 的工作电压范围,最大充电电流可达 600mA,充电终止电压为 4.2V,工作温度覆盖 -40℃+85℃,静态电流仅 50μA,适合低功耗和成本敏感的应用场景。

二、主要规格参数

  • 芯片类型:充电芯片(锂电池专用)
  • 输入/工作电压:3.9V ~ 6V
  • 适配电池:锂离子电池,单节(1S)
  • 最大充电电流:600mA(可通过外部电阻设定)
  • 充电饱和/恒压电压:4.2V(典型终止电压)
  • 工作温度:-40℃ 至 +85℃
  • 静态电流(Iq):50μA(低静态漏电,有利于待机寿命)
  • 封装:SOT-23-5
  • 品牌:LOWPOWER(微源半导体)

三、功能与特点

  • 适配单节锂电池的标准 CC/CV 充电架构,保证对电池的安全充电与寿命保护。
  • 最大充电电流 600mA,满足主流小型便携设备的充电需求。
  • 低静态电流设计(50μA),在设备关机或待机时可降低电池自放电对系统续航的影响。
  • 宽工作电压范围(3.9V~6V),兼容多种 USB 供电或外部电源方案。
  • 宽温度范围,适合工业级和消费级多种环境。

四、典型应用

  • 蓝牙耳机、可穿戴设备、运动手环等超小型便携设备;
  • 小型医疗设备、手持终端;
  • 便携式传感器、数据采集模块和其他需要单节锂电池供电的电子产品。

五、使用建议与注意事项

  • 为设定充电电流,需要按照数据手册通过外接电阻(或电流检测电阻)进行精准配置,勿超过 600mA 的额定值以避免芯片或电池过热。
  • 输入电源应稳定且滤波良好,建议在输入端并联陶瓷/钽电容以抑制瞬态和反向干扰。
  • 由于芯片封装为 SOT-23-5,散热受限。高充电电流下需注意 PCB 散热设计,增加铜箔面积或热过孔以降低结温。
  • 推荐在电池端加入必要的保护电路(如保护 IC 或熔断器)以防止过放、短路等异常情况。
  • 工作电压范围必须严格控制在 3.9V~6V 之间,超过此范围可能损坏芯片或引发安全隐患。
  • 在极端温度环境(尤其高温)下,应关注充电效率与热关断机制,必要时做降额设计。

六、封装与采购

  • 封装型号:SOT-23-5,便于自动贴片和小型化设计。
  • 适合批量采购与贴片生产,建议参考厂商的正式数据手册获取引脚定义、典型应用电路和推荐外部元件值以完成硬件设计与调试。

总结:LP4060B5F 以其低静态电流、600mA 的充电能力和紧凑 SOT-23-5 封装,适合对体积和功耗敏感的单节锂电池应用。设计时应重视输入滤波、散热和电流设定,配合合适的电池保护策略以确保系统可靠性。请以厂家数据手册为准进行最终电气与热设计验证。

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
