CN3130 产品概述
一、产品简介
CN3130 是 CONSONANCE（上海如韵）推出的一款小功率充电管理芯片，封装为 SOT-23-6，专为单节锂电池体系（特别是磷酸铁锂 LiFePO4）提供稳定、可靠的充电控制。芯片针对便携、低功耗场景优化，体积小、静态电流低，适合空间受限和电源预算严格的应用。
二、主要参数
- 芯片类型：充电芯片（电池管理）
- 工作电压范围：3.9 V ～ 6 V
- 最大充电电流：300 mA
- 充电饱和电压：3.3 V（适配 LiFePO4 单节）
- 适用电池类型：磷酸铁锂（LiFePO4）及一般锂电池（单节）
- 电池节数：1 节
- 工作温度：-40 ℃ ～ +85 ℃
- 静态电流（Iq）：约 3 μA
- 封装：SOT-23-6
- 品牌：CONSONANCE（上海如韵）
三、主要功能与特点
- 适用于单节电池的恒流-恒压充电（CC-CV）架构，能提供最高 300 mA 的充电电流。
- 专用 3.3 V 充电终止电压，符合 LiFePO4 单节充电要求，避免过压。
- 极低的静态电流（约 3 μA），在待机或电池备用时能最大限度降低自耗。
- 小封装（SOT-23-6），便于集成到体积受限的设备中。
- 宽工作温度范围，适应工业级与消费电子环境。
四、典型应用
- 便携式测量仪器、无线传感器节点（IoT）、低功耗穿戴设备。
- 小型手持设备、应急照明、备用电源电路。
- 需要单节 LiFePO4 电池管理的小型消费类与工业设备。
五、设计建议与注意事项
- 输入电源应高于充电饱和电压并在芯片工作电压范围内（3.9–6 V）；为保证稳定性，建议添加输入去耦电容。
- 按照数据手册配置充电电流设定电阻或程序引脚，避免超过 300 mA 的额定值以防发热或损坏。
- 关注散热与封装周围布局，高电流充电时应评估 PCB 温升。
- 电池温度监测与必要的保护电路（如过充、过流、热关断）应按系统安全设计要求配置，具体保护特性及实现方式请参照芯片数据手册和参考设计。
更多详细电气特性、引脚定义和参考电路请查阅 CN3130 数据手册，以确保在目标应用中正确、安全地使用该芯片。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
