ME2808A36M3G 产品概述
一、产品简介
ME2808A36M3G 是 MICRONE（南京微盟）推出的一款三端低功耗电压检测器，采用 NMOS 制程实现。器件为固定阈值型电压监测元件，阈值电压为 3.6V，输出为开漏（Open-drain），复位信号为低电平有效。封装为 SOT-23，适用于对单路电源进行可靠的欠压检测与复位控制。
二、主要规格亮点
- 芯片类型：电压检测器（电源复位监控）
- 阈值电压：3.6V（固定）
- 输出类型：开漏（需外部上拉）
- 复位有效电平：低电平有效（VMON < VTH 时输出低电平）
- 工作电压范围：1.5V ~ 18V（宽范围供电，适配多种系统）
- 受监控电压数：1 路
- 静态电流（Iq）：典型 1.8μA（适合电池供电等低功耗场景）
- 工作温度范围：-40℃ ~ +85℃（TA）
- 封装：SOT-23，体积小，便于表贴装配
三、功能与工作原理
ME2808A36M3G 对单路被监控电压进行连续比较，当被监控电压（VMON）低于 3.6V 阈值时，器件将输出低电平复位信号（开漏拉低）。当 VMON 回升并超过阈值并满足内部复位释放条件后，开漏输出释放为高阻态，通过外部上拉电阻恢复为高电平，从而通知系统恢复正常工作。开漏输出可与系统逻辑电平兼容，便于与不同电压域的微控制器或电源管理电路接口。
四、典型应用场景
- MCU/CPU 复位与电源上电监控
- 电池供电设备的欠压保护与电量监测（便携设备、可穿戴）
- 电源管理、电源智能切换与电源序列控制
- 工业与通信设备中的电源可靠性检测（适用于最高 18V 的电源）
- 物联网终端、传感器节点、低功耗系统
五、使用建议与布局要点
- 由于输出为开漏，需在输出端接上拉电阻以生成逻辑高电平；常见上拉阻值范围为几十千欧到几百千欧，具体取值应依据系统输入阻抗和响应速度权衡选取。
- 建议将芯片靠近被监控电源点放置，减少感应与压降带来的检测误差。
- 在电源输入处并联 0.1μF 陶瓷缓冲电容以抑制瞬态噪声，提高检测稳定性。
- 对于噪声较大的电力环境，可在检测输入与地之间增加 RC 滤波以避免误触发，但需注意不要影响响应时间。
- PCB 布局注意保持检测引脚附近的地平面完整，避免长走线带来的干扰。
六、优势概述
ME2808A36M3G 结合了低静态功耗（1.8μA）、宽工作电压（1.5~18V）与固定 3.6V 检测阈值的特点，适合对 3.6V 级别电源进行可靠监控的低功耗系统。小封装（SOT-23）和开漏输出使其在多种应用中具有良好的兼容性与使用灵活性。

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.
