LP6304BQVF 产品概述

一、概述

LP6304BQVF 是微源半导体(LOWPOWER)面向单节锂电池充电管理的高度集成器件。其工作电压范围为 2.2V 至 5.5V,最大充电电流可达 2A,适合为单节 Li-Ion / Li-Poly 电池提供稳健的恒流-恒压(CC/CV)充电支持。器件工作温度覆盖 -40℃ 到 +85℃,静态电流(Iq)仅为 280µA,利于低功耗应用。

二、主要规格亮点

  • 供电范围:2.2V ~ 5.5V,适配 USB 与电池供电环境;
  • 最大充电电流:2A,支持快充场景;
  • 电池类型:单节锂电池(1S);
  • 不支持电池温度检测与 0V 唤醒充电(需外部方案处理);
  • 静态电流:280µA,利于节能待机;
  • 封装:QFN-24-EP (4×4),带焊盘利于散热与 PCB 链接;
  • 工作温度:-40℃ ~ +85℃,适配工业与消费类环境。

三、典型应用场景

  • 便携式消费电子(蓝牙耳机、手持终端);
  • 可穿戴与健康监测设备;
  • 小型移动电源与便携充电器;
  • 物联网终端与无线传感器节点;
  • 需要 1 节锂电高效充电的电源管理模块。

四、设计要点与建议

  • 输入与输出旁路电容应按资料书建议布置,靠近器件电源引脚以保证稳定性与抑制噪声;
  • 若采用外接电阻设定充电电流,请参考厂方数据计算并选用额定功率足够的分流电阻;
  • QFN-24-EP 封装需良好底部焊盘(exposed pad)与多层 PCB 的散热通道,必要时铺铜并过孔下 through-via 提高热导;
  • 由于器件不支持 0V 唤醒充电,若需对深度放电电池进行预充,应外加前置电路或选择具备该功能的替代方案;
  • 不支持电池温度检测时,若环境或安全要求较高,应外接热敏监测或在系统层面实现温度保护;
  • 静态电流 280µA 在断电待机或长期连接电池时仍会引起自放电影响,需在系统功耗预算中考虑该项消耗。

五、封装与可靠性考量

QFN-24-EP (4×4) 封装利于小面积布局并提供良好热性能。器件额定工作温度宽泛,适宜在苛刻环境下使用;在布局时建议保证良好接地和散热路径,并按照可靠性测试要求进行温度循环与电气老化验证。

六、总结

LP6304BQVF 为单节锂电池提供了高电流充电能力与较低静态功耗的平衡方案,适合对体积、效率与成本有要求的便携与 IoT 应用。设计时应注意其不支持电池温度检测与 0V 充电的限制,并在 PCB 热管理与外围保护电路上做相应策略以保障系统可靠与安全。若需详细电气参数、引脚定义与典型应用电路,请参考厂方数据手册或联系微源半导体获取技术支持。

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
