ETA6003Q3Q 产品概述
一、产品简介
ETA6003Q3Q 是钰泰（ETA）推出的一款单节锂电池线性/开关混合充电管理芯片，针对便携式电子设备充电需求优化设计。芯片工作电压范围为 4.4V～5.5V（适配USB 5V），最大充电电流 2A，充电终止电压 4.20V，支持对 0V 深度放电电池的唤醒充电，工作温度范围 -40℃～+85℃，静态电流仅 70µA，封装为 QFN3×3-16，适合空间受限的移动设备方案。
二、主要特点
- 最大充电电流：2A，满足中高速充电需求
- 低静态电流：Iq = 70µA，有利于系统待机耗电优化
- 充电模式：典型 CC–CV 充电策略，终止电压 4.20V
- 0V 电池充电支持：可对深度放电电池进行唤醒
- 电池温度检测：支持 NTC 温度监测，提高充电安全性
- 工作环境：-40℃～+85℃，适应宽温应用场景
- 封装：QFN3×3-16，利于小尺寸产品的散热与布板
三、工作原理概述
ETA6003Q3Q 以恒定电流-恒定电压（CC–CV）策略对单节锂电池充电：先以设定电流对电池充电（CC），当电压上升至 4.20V 时转为恒压（CV）并逐步降低电流直至终止。芯片内置对 0V 电池的唤醒方案与电池温度检测接口（NTC），在温度或电压异常时可禁止充电以保障安全。
四、封装与热管理
QFN3×3-16 小封装利于高密度 PCB 设计，但充电时产生的功耗需通过铜厚和底部热焊盘散热。建议在 PCB 底部开大焊盘并多层过孔连通散热层，同时输入侧做合适的陶瓷电容旁路，提升热稳定性和电源抑制。
五、典型应用
- 移动电源、便携蓝牙音箱、智能穿戴
- 手持终端、无线鼠标、低功耗物联网终端
- 需要 2A 级别充电且空间受限的消费电子产品
六、设计建议与注意事项
- 输入供电建议使用稳压 5V ±0.5V 的电源，注意限流与熔断保护；
- 采用适配的充电电流设定与限流措施，实际电流应根据热预算和电池规格调整（不得超过 2A）；
- 在电池负端或指定位置连接 NTC 以实现电池温度监测；
- 布局时将充放电感性元件、热源与敏感信号分隔，电流路径短且宽；
- 在产品验证阶段做全温度、过充、短路及长时间充放电测试，确保可靠性。
ETA6003Q3Q 以其低静态电流、支持 0V 唤醒和温度检测的特性，适合对安全与能耗有较高要求的单节锂电池便携设备。具体引脚定义、典型电路与器件选型建议，请参见厂商数据手册与参考设计。

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.
