MAX811LEUS+T 是一款用于微处理器/微控制器供电监控的电压监督器(Processor Supervisor),由 ADI/LINEAR 提供。器件在 VCC 下降到设定阈值时输出复位信号,支持手动触发复位功能,采用 4 引脚 SOT-143 封装并以卷带方式(T/R)供货,适合空间受限的嵌入式与电池供电系统。
当 VCC 低于 4.63 V 时,器件将把 RESET 输出拉低,保持系统处于复位状态;当 VCC 回升并稳定超过阈值,经过内部 140 ms 的复位超时延迟后释放 RESET,使被监控微控制器安全启动。MR 引脚可通过外部开关或开漏输出拉低以强制复位;释放 MR 后同样经过内部延时释放 RESET。推挽输出能直接驱动目标器件的复位引脚,无需外部上拉电阻。
器件采用 4-pin SOT-143 封装,尺寸小巧、适合集成到空间受限的 PCB 布局中。标识型号为 MAX811LEUS,后缀 +T 表示卷带(Tape & Reel)包装,便于自动贴片生产。
型号:MAX811LEUS+T(4-pin SOT-143,卷带包装)
品牌:ADI / Linear(原 Maxim 产品线)
在选型时请确认阈值、复位延时与封装与系统要求匹配,如需更详细的电气特性(阈值容差、滞后、上电/掉电行为曲线等),请参考官方数据手册或联系供应商技术支持。

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.
