DW03 产品概述

一、产品简介

DW03 是 Slkor(萨科微) 面向单节锂电池保护的专用保护芯片,采用 SOT-23-5 封装,适用于对体积和功耗有严格要求的便携类电子产品。芯片支持 0V 低电压电池充电,工作温度范围宽(-40℃ ~ +85℃),静态电流仅 1.5 µA,能够在长期待机场景下有效延长电池寿命与设备寿命。

二、主要参数

  • 芯片类型:保护芯片
  • 电池类型:单节锂电池(1S)
  • 工作电压:3.6V ~ 4.4V
  • 放电截止电压:2.4V
  • 0V 电池充电:支持
  • 静态电流 (Iq):1.5 µA
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOT-23-5
  • 品牌:Slkor(萨科微)

三、保护功能概述

DW03 提供锂电池应用中常见的安全保护功能,包括过充保护、过放保护、过流/短路保护等。支持当电池被深度放电至 0V 时仍可被充电恢复,且低静态电流有利于长时间储存或低功耗终端使用。芯片的保护逻辑使输出在异常时切断放电路径,避免电池损伤或安全风险。

四、适用场景

适合单节锂电池供电的便携设备与智能终端,例如:

  • 可穿戴设备、蓝牙耳机
  • 低功耗物联网终端、传感器节点
  • 小型充电宝、应急电源模块
  • 智能门锁、手持设备、医疗便携设备

五、设计与使用建议

  • 根据电池化学特性与安全要求,合理设置充放电阈值,与充电管理系统配合校准;芯片工作电压范围(3.6V–4.4V)可作为设计参考。
  • 为保证可靠的过流/短路保护,选择与芯片匹配的低 Rds(on) 功率 MOSFET,并注意 FET 的耐压与热耗散能力。
  • 在 PCB 布局上,尽量将电池连接、MOSFET 以及电流路径缩短,增大铜箔面积以降低温升;在靠近电池端的地方加放滤波与抑制元件以抑制瞬态干扰。
  • 出厂或运输时可利用芯片对电池的深放电保护,延长电池寿命,同时注意在检修或生产测试时提供可控的复位/激活方案。

六、可靠性与测试要点

  • 在温度极限(-40℃ / +85℃)下验证芯片的保护触发与恢复行为。
  • 做实际负载短路与过流测试,确认保护动作速度与恢复特性满足产品安全规范。
  • 对支持 0V 充电的产品,应验证在不同输入电源条件下的充电启动可靠性与兼容性。

总结:DW03 以超低静态电流、宽温度范围和对 0V 电池的支持为主要卖点,适用于对功耗和体积敏感的单节锂电池产品。合理的外围器件选型与 PCB 布局是保证整体性能与可靠性的关键。若需进一步的引脚定义、典型电路或阈值曲线,请提供器件数据手册或授权图纸以便给出更精确的设计建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
