ME2808A44M3G 是南京微盟(MICRONE)推出的一款三端低功耗电压检测器,采用 NMOS 工艺实现,适用于需要可靠复位信号与电压监控的各类电子系统。器件采用 SOT-23 封装,具有宽工作电压、极低的静态电流和开漏输出,特别适合电池供电与低功耗设计场景。
ME2808A44M3G 内部集成了高精度低功耗参考源、比较器、迟滞(Hysteresis)电路与输出驱动器。工作时,参考源提供稳定的比较基准,比较器将被监控电压与该参考值比较;迟滞回路有效抑制输入噪声与抖动,避免输出在阈值附近频繁切换。输出采用开漏结构,便于与外部上拉电阻或总线线(如 I2C、开集电极总线)配合使用,支持多路器件线或有选择地拉高到任意合适的逻辑电平。
总结:ME2808A44M3G 以其 4.4V 固定阈值、1.8 µA 的超低静态电流、宽工作电压(1.5V~18V)与开漏输出特性,为电源监控与可靠复位应用提供了简单、稳定且低功耗的解决方案。其 NMOS 工艺与内置迟滞设计进一步提升了在复杂电磁与电源环境下的可靠性。详细电气特性、引脚排列与应用电路建议请参考 MICRONE 官方数据手册。

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.
