LP4056HSPF 产品概述

一、产品简介

LP4056HSPF 是微源半导体(LOWPOWER)面向单节锂离子/聚合物电池的高集成充电管理芯片。芯片工作电压范围为 4.5V~6.5V,采用 ESOP-8 封装,集成必要的充电控制功能与电池温度检测接口,适用于各种便携式与低功耗电源管理场景。

二、主要性能参数

  • 芯片类型:充电芯片(单节锂电池)
  • 工作电压:4.5V ~ 6.5V
  • 最大充电电流:1A(可通过外部元件设定)
  • 充电饱和电压(终止电压):4.2V
  • 静态电流(Iq):1uA(超低静态电流,利于待机能耗优化)
  • 电池节数:1 节
  • 工作温度:-20℃ ~ +85℃
  • 电池温度检测:支持(通常接热敏电阻/NTC实现温度监控)
  • 封装:ESOP-8

三、功能特色

  • 支持恒流-恒压(CC/CV)充电,精确控制充电过程直至电池充满为止;
  • 最大 1A 充电能力,满足中小功率便携设备快速充电需求;
  • 超低静态电流(1uA),在无输入或待机状态下对电池几乎无额外耗损;
  • 内置电池温度监测接口,可在过冷或过热时自动限制或停止充电,提升安全性;
  • 宽输入电压适配常见 USB 与外部电源,设计灵活性高。

四、典型应用场景

适用于单节锂离子/聚合物电池供电的各类产品,例如:

  • 便携式消费电子(蓝牙音箱、便携播放设备);
  • 智能家居与物联网终端(无线传感器、智能遥控器);
  • 可穿戴设备与小型医疗设备;
  • 小型备用电源与充电宝单体管理电路。

五、封装与热管理

ESOP-8 封装在保持小体积的同时具备较好的热散能力。实际布局时建议:充分利用 PCB 散热铜箔、靠近电源管脚铺铜,合理布局输入/电池去耦电容与检测电阻,以保证在最大充电电流下的热稳定性与可靠性。

六、设计注意事项

  • 充电电流通过外部编程电阻或设计开关设置,设定时需考虑输入电源能力与系统发热;
  • 严格按照数据手册选配输入/输出去耦电容与滤波元件,保证稳定工作与抑制噪声;
  • 电池温度检测应使用符合芯片规格的热敏元件(NTC),并校准温度阈值以防误判;
  • 系统级建议增加熔断、反接保护与电池短路保护电路,提升整体安全性。

七、总结

LP4056HSPF 以其宽输入电压范围、1A 最大充电能力、4.2V 精确终止以及超低静态电流和电池温度检测功能,成为单节锂电池充电管理的实用解决方案。适配多类便携与低功耗应用,且 ESOP-8 封装利于工业化量产与热管理设计。欲获得最佳性能与安全性,请参照厂商数据手册与参考设计进行电路与 PCB 布局。

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
