ME2808A27M3G 是南京微盟(MICRONE)推出的一款单通道电压检测器(Voltage Detector),采用 SOT-23 封装。器件对单一路被监控电压进行阈值检测,当电源电压低于设定阈值 2.7V 时输出有效复位信号(低电平有效);输出为开漏结构,静态工作电流极低(Iq = 1.8μA),工作电压范围宽(1.5V ~ 18V),工作温度范围 -40℃~+85℃(Ta)。
ME2808A27M3G 在被监控电压(VCC)低于 2.7V 时将 RESET 引脚拉至低电平,正常供电时输出释放(开漏浮空),需外接上拉电阻至系统逻辑电平。常见上拉电阻值为 10kΩ 至 100kΩ,具体取值依据上拉电源与所需上升时间决定。器件本身不含复位延时或看门狗功能,如需更长的复位保持时间,可在复位线上加 RC 滤波或使用独立复位延时电路。
典型电路建议:
ME2808A27M3G 采用 SOT-23 小型封装,通常为三引脚布局(VCC、GND、RESET)。在实际设计中请参照官方数据手册确认引脚定义和封装尺寸,便于 PCB 布局与焊接。选型时注意阈值(2.7V)是否匹配系统电源等级及上电/欠压保护要求。
如需器件原厂数据手册、引脚图或典型应用电路图,可进一步提供,我会协助核对参数并给出元件选型与布局建议。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
