CN3165 产品概述
CN3165 是 CONSONANCE（上海如韵）面向单节锂电池充电管理的电源管理芯片，封装为 DFN-8-EP(3×3)。该器件工作电压宽，待机电流极低，并且支持电池温度检测，适合对能耗、尺寸和安全性有较高要求的便携式与嵌入式产品。
一、主要参数一览
- 芯片类型：充电管理芯片
- 输入工作电压：4.4V ～ 6V（适配常见 5V USB 电源）
- 充电饱和电压（终止电压）：4.2V（单节锂离子电池）
- 电池类型/节数：锂电池，1 节
- 支持电池温度检测：是（支持外接热敏元件/NTC）
- 静态电流（Iq）：3 μA（极低待机功耗，有利于长待机产品）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 封装：DFN-8-EP (3×3)
- 品牌：CONSONANCE（上海如韵）
二、功能与特点
- 低静态电流：3 μA 的待机电流，使电池在未工作或待机状态下的自放电更低，延长系统待机时间。
- 宽输入电压范围：4.4V～6V，兼容常见 USB 或适配器电源，系统适配性强。
- 标准充电终止电压：4.2V，符合单节锂离子电池充电规范。
- 温度监测支持：可接入电池温度检测电路（如 NTC），实现充电温度保护，提升充电安全性。
- 耐温性能良好：工作温度覆盖工业级范围，适合室内外及工业环境应用。
- 紧凑封装：DFN-8-EP (3×3) 适合高密度 PCB 布局与热性能优化。
三、典型应用场景
- 便携电子：蓝牙耳机、智能手表、健身追踪器等对功耗敏感的可穿戴设备；
- 小型消费电子：无线鼠标、遥控器、便携式传感器节点；
- 物联网终端：电池供电的传感器、监测设备和智能家居终端；
- 小容量移动电源与备用电池管理。
四、设计与布板建议
- 电池温度检测端建议靠近电池位置布局，使用短、低阻抗走线连接 NTC，以保证测温准确性。
- 封装为 DFN-8-EP，底部有散热焊盘（EP），建议在 PCB 对应位置做金属焊盘并配合多层过孔或散热铜箔以利热量分散。
- 输入电源端与电池端应配置合适的输入滤波与旁路电容，减小纹波并提高稳定性。
- 若需要设置充电电流，建议参考芯片数据手册采用外置电阻或电流设定网络（CN3165 常见设计方式为通过外部元件调整工作参数）。
五、选型和注意事项
- 若系统需支持多节电池或更高充电电流，应选择多节或大功率充电管理芯片；
- 对于对充电效率和热管理有严格要求的应用，评估芯片在最大充电电流下的热耗散能力并进行相应的 PCB 散热设计；
- 使用温度检测功能时，必须校准并验证温度阈值以满足电池厂商的安全要求；
- 详细电气规范、引脚定义及推荐外设值请参阅 CONSONANCE 官方数据手册。
总结：CN3165 以其低待机电流、支持温度检测和工业级工作温度，适用于对体积、功耗和安全性有要求的单节锂电池供电产品。合理的 PCB 布局和温度保护设计能充分发挥该器件在便携与物联网产品中的优势。

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.
