LP28303AQVF 产品概述
一、概述
LP28303AQVF 是微源半导体（LOWPOWER）面向单节锂电池充电应用的线性/开关（注：实际拓扑以设计文档为准）充电管理芯片。芯片支持常见的锂离子电池恒流-恒压（CC/CV）充电策略，输入工作电压范围为 4.5V ~ 5.5V，充电截止电压为 4.2V（针对单节锂电池），最大可提供 2.5A 的充电电流，适用于对充电速度有较高要求的便携类设备。
二、主要规格（基于提供参数）
- 芯片类型：充电芯片
- 输入工作电压：4.5V ~ 5.5V
- 最大充电电流：2.5A
- 充电饱和电压（终止电压）：4.2V（单节）
- 电池类型：锂电池（单节）
- 电池节数：1
- 工作温度范围：-20 ℃ ~ +85 ℃
- 电池温度检测：支持（可接外部温度传感器/NTC）
- 静态电流（Iq）：100 μA（待机低功耗）
- 品牌：LOWPOWER（微源半导体）
- 封装：TDFN-10-EP（3 × 3 mm）
三、功能与优势
- 支持单节锂电池标准的 CC/CV 充电流程，终止电压 4.2V，兼容主流移动电源与便携终端电池包；
- 最大 2.5A 充电能力，能满足手机、蓝牙音箱、小功率移动电源等对充电速率的需求；
- 低静态电流（约 100 μA），在无载或待机时有利于延长系统电池寿命；
- 支持电池温度检测，可通过外接 NTC 等实现温度范围保护，提升充电安全性；
- 小尺寸 TDFN-10-EP（3×3）封装，适合空间受限的便携设备设计。
四、设计注意事项
- 输入电源要求稳定在 4.5V~5.5V，推荐设计良好的输入滤波与过压保护以保障充电稳态；
- 最大 2.5A 充电电流会产生一定热耗，PCB 布局需注意散热（大焊盘、散热铜箔、EP 地垫）及器件功耗限制；
- 充电电流通常通过外部电阻或检测电阻设置，需按应用需求选择合适的分流电阻并保证其额定功率；
- 电池温度检测引脚需正确接入温度传感器（NTC）并根据电池厂商建议配置温度阈值，避免极端温度充电；
- 推荐在输入端和电池端分别配置合适的去耦电容与滤波网络，保证充放电过程稳定。
五、典型应用场景
- 智能手机与平板类单节电池快速充电模块；
- 便携式电源、移动电源（单节/并联方案时需评估）；
- 蓝牙音箱、可穿戴设备及各类手持终端的电池管理；
- 需要平衡充电效率与待机功耗的便携式电子产品。
总结：LP28303AQVF 以其 4.5V~5.5V 的输入适配范围、最高 2.5A 的充电能力、低待机电流和电池温度检测支持，适合对充电速度与安全性有较高要求的单节锂电池便携设备。具体电路设计和可靠性验证建议参考厂商原理图与详细数据手册并进行温度与寿命测试。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
