BRCL3130ME 产品概述
一、产品概况
BRCL3130ME 是 BLUE ROCKET 推出的单节锂电池保护芯片，采用 SOT-23-5 封装，面向资源受限、对待机功耗和安全性有较高要求的便携式电源方案。芯片设计用于保护单节锂离子/锂聚合物电池并支持从深度放电（0V）状态恢复充电，适合低功耗长寿命电池供电设备。
二、主要特性
- 极低静态电流：Iq = 1.5 μA，利于延长电池待机时间。
- 支持 0V 电池充电：可对深度放电的电池进行唤醒充电。
- 充电饱和电压：4.3 V（芯片内部设定或与充电回路配合的目标电压）。
- 工作电压范围：3.6 V ~ 6 V，兼容单节锂电池及上游充电/保护供电范围。
- 放电截止电压：2.4 V（电池保护触发的下限参考）。
- 工作温度范围：-40 ℃ ~ +85 ℃，适应广泛应用环境。
- 封装与可靠性：SOT-23-5 封装，功耗 Pd = 400 mW，具备 2 kV ESD 抗扰度（规格表述）。
三、功能简介
作为一款电池保护芯片，BRCL3130ME 通常用于实现单节电池的基本安全管理功能，包括过放（放电截止）、过充保护与充电控制，以及过流/短路保护策略（具体阈值与响应时间以正式数据手册为准）。不支持电池温度检测功能（无内部热敏输入），因此在需要温度监控的充电场景应配合外部热敏元件或充电器实现温度保护。
四、封装与热管理
SOT-23-5 紧凑封装适合小型 PCB 布局。芯片额定功耗 Pd = 400 mW，建议在 PCB 布局时留出适当的铜面积以利于散热，并将器件放置于靠近电池与外部连接处以减少走线电阻与压降对保护动作的影响。
五、典型应用
- 低功耗物联网终端、传感器节点
- 可穿戴设备与健康监测终端
- 便携式消费电子（蓝牙耳机、遥控器等）
- 小型移动电源与备用电源管理模块
六、使用建议与注意事项
- 在需严格控制充电终止电压的系统中，请确认充电器与本芯片的 4.3 V 充电饱和电压是否匹配；如使用标准 4.2 V 流程，应复核兼容性。
- 由于不支持电池温度检测，建议在高功率或复杂环境充电场景中加入外部温度监测与充电器联动。
- 对于较大充放电电流或短路保护要求严格的应用，应配合外部限流器件（熔断器、MOSFET、限流电阻等）使用，并参考芯片数据手册中的最大允许电流与热限值。
- 推荐在设计初期获取并研读 BRCL3130ME 的完整数据手册以确认保护阈值、延时与典型电路示例，确保系统稳定与安全。
七、总结
BRCL3130ME 是一款面向单节锂电池的低静态电流保护芯片，具备 0V 唤醒充电支持、宽工作温度和紧凑 SOT-23-5 封装，适合对待机寿命和尺寸有要求的便携设备。设计时应注意充电电压匹配与热管理，并在必要时补充外部温度检测与限流保护以满足更严格的安全规范。若需具体阈值和时序参数，请参考 BLUE ROCKET 提供的正式数据手册。

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.
