MAX811REUS+T 是一款用于微处理器和数字系统的电压监控器(Processor Supervisor),对单路电源进行监控,并在电源异常或手动触发时产生低电平有效复位信号。器件工作电压范围宽(1.0V 至 5.5V),静态电流仅约 10 µA,适合电池供电和低功耗系统使用。封装为 SOT-143-4,带卷带包装(+T)。
MAX811REUS+T 在供电电压跌破 2.63 V 时将输出一个低电平复位信号,保持约 140 ms,以保证系统在电源恢复后有足够的时间复位并进入稳定工作状态。器件输出为开漏结构,需通过外部上拉抵达所需逻辑电平;手动复位输入允许外接按键或外部逻辑直接触发复位(通常为拉低触发),便于系统维护与调试。低静态电流使其在待机或低功耗模式下对电池影响极小。
该型号采用 SOT-143-4 小封装,适合空间受限的 PCB 设计。后缀 +T 表示卷带包装(Tape & Reel),便于自动贴片生产线使用。品牌归属 ADI(原 Maxim/Linear 系列),在采购时请核对完整型号与供应商信息以保证版本与参数一致。
总结:MAX811REUS+T 以其固定的 2.63 V 门槛、140 ms 复位保持时间和极低的静态电流,适合对单路电源进行可靠复位管理的低功耗系统。配合合理的上拉、电源旁路和手动复位设计,可在多种嵌入式与便携式应用中提高系统的上电可靠性与抗毛刺能力。

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.
