LP4076SPF 产品概述

一、产品简介

LP4076SPF 是 LOWPOWER(微源半导体)推出的单节锂电池充电管理芯片,针对便携类小功率设备的锂电池充放电管理设计。芯片工作电压范围为 4.5V ~ 6V,最高支持 1A 的充电电流,充电终止电压 4.2V。器件封装为 ESOP-8,工作温度范围为 -20℃ 至 +85℃,并支持电池温度检测功能,适用于对安全性与充电效率有要求的应用场景。

二、主要特性

  • 输入电压范围:4.5V ~ 6V,适配常见 USB 5V 或受控电源输入。
  • 最大充电电流:1A,满足多数单节锂离子电池的快速充电需求。
  • 充电饱和电压:4.2V(典型单节锂电池规范终止电压)。
  • 电池节数:单节锂电池(1S)专用。
  • 支持电池温度检测:兼容外部温度传感器(如 NTC),用于充电温度范围判断与保护。
  • 宽工作温度:-20℃ 至 +85℃,适应户外及工业级应用环境。
  • 封装:ESOP-8,便于自动化贴片装配并有利于散热布局。

三、功能与保护(典型)

LP4076SPF 面向锂电池安全充电,通常具备以下功能(实际请以厂商资料为准):

  • 恒流/恒压(CC/CV)充电控制,终止于 4.2V。
  • 可编程或固定的最大充电电流,最高 1A。
  • 电池温度检测(NTC)输入,支持在过冷/过热情况下停止或限制充电。
  • 热调节或限流保护,防止在高温或散热受限时过热。
    (注:具体的软启动、欠压、短路与状态指示等细节请参阅官方数据手册。)

四、典型应用场景

  • 便携式蓝牙音箱、耳机底座、手持设备的单节锂电池充电管理。
  • 小型移动电源、智能家居传感器、玩具和可穿戴设备。
  • 工业或商用设备中的后备电源充电模块,需在宽温度下稳定工作。

五、设计与布局建议

  • 电源与电池端应配置适当的输入/输出电容,靠近芯片引脚放置以抑制噪声与稳定环路。
  • 若为最高充电电流(接近 1A)工作,需在 PCB 上做好散热设计:增大铜箔面积、在芯片下方或周围使用散热过孔或加散热铜层。
  • 电池温度检测建议使用标准 10k NTC(常见类型),并将 NTC 与电池紧密贴合以获得准确温度采样。
  • 引线与电源轨尽量短且宽,电流感测电阻(如存在)应靠近芯片布置并选用低温漂类型。
  • 对于 USB 供电场景,注意输入侧的过压及反向保护设计,必要时外加热熔断或保险元件。

六、使用注意事项

  • 输入电压不得长时间超过 6V 或低于 4.5V,以免影响充电工作状态或损伤芯片。
  • 充电电流不应超过芯片标称最大值 1A,且电池本身应兼容相应充电速率。
  • 芯片在高温环境下可能采取热调节,带来充电电流下降,应在系统级测试中验证充电曲线与温升。
  • 在量产前应参考并严格遵循 LOWPOWER 提供的原理图、布局建议与测试流程。

七、资料与选型建议

选择 LP4076SPF 时,建议获取并研读最新的官方数据手册,核对电气特性曲线、引脚定义与典型应用电路;在样机阶段进行温升、充放电曲线与电池兼容性测试。若需替代或更高功率方案,可与 LOWPOWER 或代理商沟通以获得相关推荐与技术支持。

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
