EG4005C 产品概述
一、产品简介
EG4005C 是屹晶微（EG）推出的一款微波与红外复合感应处理芯片，集成两路传感信号处理算法，专为人体移动侦测与环境感知设计。芯片工作电压宽范围为 3V ~ 5.5V，静态工作电流典型值仅 75 μA，工作温度范围 -40 ℃ ~ +85 ℃，采用 SOP-8 封装，便于标准化生产与应用布板。
二、主要特性
- 支持微波（雷达）与红外（PIR）信号的前端处理与融合判决，提高误报抑制能力。
- 宽电源范围 3V~5.5V，适配常见电池与稳压供电方案。
- 超低工作电流（75 μA），适合电池供电和能量受限的终端设备。
- 工业级温度范围（-40 ℃~+85 ℃），可靠性高，适用于户内外各种环境。
- SOP-8 封装，兼顾散热与焊接可靠性，便于自动化贴装。
三、典型应用
- 安防与入侵检测：门禁周界、报警探头、周界震动与运动检测。
- 智能照明与能耗管理：基于人体存在检测的自动开关灯、节能控制。
- 智能家居与楼宇自动化：人体感知、场景激活、无人开启与关闭控制。
- 工业与商业场合：人员计数、区域占用检测、设备联动触发。
四、设计与使用建议
- 电源管理：芯片对电源纹波敏感，建议在电源引脚并联 0.1 μF 陶瓷电容和 4.7 μF 以上电解或钽电容做旁路与滤波。
- 外围器件：微波和红外前端模块应合理布局，天线与热释电探头尽量避免相互屏蔽与干扰。
- PCB 布局：须注意信号地和模拟地分割，尽量缩短敏感信号走线，避免与大电流回路并行。
- 抗静电、防潮：产品在生产与运输过程中注意 ESD 防护与防潮包装，延长器件寿命。
五、封装与采购
EG4005C 使用 SOP-8 标准封装，支持自动贴片与回流焊接；常见订购形式为卷盘（reel）或托盘（tray）。在批量采购时建议与厂商确认环境认证与质量一致性，包括 RoHS 合规与可靠性测试记录。
六、注意事项
- 在设计前端探测器时需评估环境噪声源（如空调、风扇、窗帘运动等）对微波与红外信号的影响，必要时通过物理屏蔽或算法参数调整降低误触发。
- 若需低功耗待机或唤醒控制，请结合系统电源管理方案和中断唤醒方式进行整体设计。
EG4005C 以低功耗、高可靠性与复合感知能力为核心，适合对误报率与能耗有较高要求的各类智能感知产品。若需要详细引脚定义、电气特性曲线或典型应用电路图，请联系屹晶微（EG）技术支持获取完整数据手册。

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.
