DW01 单节锂电保护芯片（SHIKUES / 时科）产品概述
一、产品简介
DW01 是一款面向单节锂离子/锂聚合物电池的保护芯片，SHIKUES（时科）品牌封装为 SOT-23-6。该芯片针对便携设备电源管理场景，提供过充、过放、过流与短路保护，支持对已被放空至 0V 的电池进行充电恢复，适用于对体积和功耗敏感的电池保护设计。
二、主要特性
- 工作电压范围：1.5V ~ 8V，适配单节锂电池及常见充电器工作区间。
- 充电饱和电压（过充点）：4.28V（检测关断阈值）。
- 放电截止电压（过放点）：2.4V（检测关断阈值）。
- 0V 电池充电支持：可对深度放电的电池进行充电恢复。
- 静态电流（Iq）：典型 4 µA，低待机功耗，适合长待机产品。
- 工作温度范围：-40℃ ~ +85℃，满足工业级和民用环境要求。
- 封装：SOT-23-6，利于小尺寸 PCB 设计与自动贴装。
三、功能说明
- 过充保护：当电池电压升至设定的过充阈值（约 4.28V）时，芯片切断充电路径，防止电压继续升高；电压降至释放阈值后自动复位。
- 过放保护：当电池电压降至放电截止阈值（约 2.4V）时，切断放电路径以防电池过放，电压回升至复位点时恢复放电。
- 过流/短路保护：对瞬时大电流或短路事件进行检测与切断，保护电池和负载安全；部分情况可实现自动恢复（视实际电路设计）。
- 充放电控制：通常与双 MOSFET（或等效功率开关）配合构成完整的充放电开关阵列，实现低压降、大电流通过与方向控制。
四、电气与环境参数（要点）
- 推荐用于单节锂电系统，需在设计中留意 MOSFET 电流承载能力与热耗散。
- 低静态电流使芯片适合长待机设备，但在高温环境下请按厂商数据手册评估漂移与可靠性。
- 支持 0V 充电功能时，应配合充电器与电流限制元件共同使用以保证安全恢复过程。
五、典型应用与设计要点
- 典型应用：移动电源、蓝牙耳机、可穿戴设备、便携式测量仪、物联网终端等单节锂电供电产品。
- 设计建议：配合规格匹配的双 MOSFET（例如集成型 FS8205A 或同等器件）使用；合理布线以减少电阻与热集中；充电器应提供限制电流与合适的协议保护。
- 布局要点：V+、V- 等电源走线应粗短直，确保温升控制；器件周围留有散热空间，滤波电容靠近芯片放置。
六、封装与采购说明
- 封装：SOT-23-6，适合自动贴装与批量生产。
- 品牌：SHIKUES（时科），采购时建议核对批次与质检报告，并参考厂商完整规格书与典型应用电路以确保最终系统可靠性。
备注：以上为概要性产品概述，设计与生产使用前请参阅 SHIKUES 官方规格书与应用手册，确认所有阈值、时序与保护行为满足目标产品需求。

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.
