ME2808A28M3G 产品概述
一、产品简介
ME2808A28M3G 是南京微盟（MICRONE）推出的三端低功耗电压检测器，采用 NMOS 工艺实现。该器件用于在系统电源电压低于设定阈值时产生复位信号，保护单片机及数字电路免受欠压错误复位或数据损坏。该型号对应固定阈值 2.8V，属于 ME2808 系列中用于 2.0V~7.0V 范围固定电压检测的成员。
二、主要规格
- 芯片类型：电压检测器（Voltage Detector）
- 输出类型：开漏（Open-drain）
- 工作电压范围：1.5V ~ 18V
- 复位有效电平：低电平有效（VCC < Vth 时输出低电平）
- 阈值电压：2.8V（固定）
- 受监控电压路数：1 路
- 静态电流（Iq）：典型 1.8 μA（低功耗设计）
- 工作温度范围：-40℃ ~ +85℃（TA）
- 封装：SOT-23（小型表面贴装）
三、功能与工作原理
当被监控电源 VCC 高于 2.8V 时，开漏输出处于高阻（需外部上拉）状态，复位释放；当 VCC 下降到低于阈值时，内部 NMOS 导通，将 RESET 拉低，发出有效复位信号。采用开漏输出可实现与多个复位源线或外部逻辑的线与（wired-OR）连接，但需外部上拉电阻或由 MCU 内部上拉提供上拉电流。
四、典型应用
- 单片机、DSP、FPGA 的上电复位与欠压保护
- 电池供电设备、电源管理模块的电压监控
- 智能家居、便携式终端、工业控制系统等需低静态电流的应用场景
典型接法：VCC 接系统电源，GND 接地，RESET 通过 10kΩ（可取 10kΩ~100kΩ）上拉至 VCC，RESET 直接接 MCU 复位脚。如需多个复位器并联，可将各开漏输出并联并共用上拉电阻，实现多源复位逻辑。
五、优势与注意事项
优势：
- 极低静态电流（约 1.8 μA），适合电池供电和低功耗设计
- 宽工作电压范围（1.5V~18V），适用性强
- SOT-23 小封装，便于空间受限的应用
- NMOS 工艺保证响应可靠、成本低
注意事项：
- 输出为开漏结构，必须外接上拉电阻；上拉电压不应超过器件允许的最大值（详见数据手册）
- 有关阈值精度、迟滞、最大漏电流和输出下拉能力等详细电气特性，请以器件数据手册为准
- 在特殊电磁/浪涌环境下建议增加去耦与防护措施以提高可靠性
六、封装与订购信息
- 品牌：MICRONE（南京微盟）
- 型号：ME2808A28M3G
- 封装：SOT-23（3 引脚）
- 订购与批量应用前建议索取并确认最新数据手册及可靠性报告，以满足设计与认证需求。

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.
