ME2808A50M3G 产品概述

一、产品简介

ME2808A50M3G 是南京微盟(MICRONE)推出的一款单路电压监控与复位芯片,封装为 SOT-23。芯片对单一电压阈值 5.0V 进行监测,当被监控电压低于阈值时输出低电平复位信号(低电平有效),输出为开漏结构,静态工作电流极低,仅 1.8 µA,适合低功耗与电池供电系统。

二、主要参数

  • 芯片类型:电压检测器(Voltage Detector)
  • 受监控电压数:1 路
  • 阈值电压:5.0 V(典型)
  • 工作电压范围:1.5 V ~ 18 V
  • 输出类型:开漏(Open-drain)
  • 复位有效电平:低电平有效
  • 看门狗定时器:无
  • 手动复位:无
  • 静态电流(Iq):约 1.8 µA
  • 工作温度:-40 ℃ ~ +85 ℃(Ta)
  • 封装:SOT-23
  • 品牌:MICRONE(南京微盟)

三、优势与特性

  1. 超低静态电流,非常适合电池供电与便携设备,待机功耗小。
  2. 宽工作电压(1.5–18V),适用范围广,从低压单芯片系统到较高电压场景皆可使用。
  3. 开漏输出支持多点共用线(wired-OR)以及与外部上拉电阻灵活配合。
  4. 单阈值、简单可靠,适合实现上电复位、欠压保护与短路异常检测等功能。

四、典型应用场景

  • 单片机/微控制器(MCU)上电复位与欠压保护
  • 电池供电设备与便携式电子产品
  • 电源管理与电压监测电路
  • 工业控制与消费类电子产品的复位电路

五、使用建议

  • 由于输出为开漏,需在复位线上外接适当的上拉电阻(常见值 10kΩ~100kΩ)拉至目标电平。
  • 建议将芯片靠近被监控的电源引脚布局,并在 VCC 处配置去耦电容以减小噪声误触发。
  • 本器件不含看门狗或手动复位按键功能,若需这些功能需外部电路或更高功能器件配合。
  • 在特殊环境或汽车类应用前,请参照完整规格书确认高温、浪涌及瞬态抗扰度等参数。

六、封装与选型

ME2808A50M3G 提供 SOT-23 小封装,适合表面贴装生产。订购与合规性、包装方式等信息请参阅 MICRONE 官方资料或向供应商咨询以获取最新数据表与可靠性验证。

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
