MAX823SEUK+T 产品概述

一、概述

MAX823SEUK+T 属于 ADI/Linear 的处理器监控器(Processor Supervisor)系列,是用于单一电源轨的电压监控与复位管理器件。器件封装为 SOT-23-5(卷带供货),适合对微控制器、DSP 和其它数字系统提供可靠的上电复位、欠压监测、手动复位和看门狗保护。

二、主要规格(基于提供参数)

  • 芯片类型:电压监控器 / 处理器监督器
  • 监控路数:1 路
  • 阈值电压:2.32 V(低于阈值时触发复位)
  • 工作电压范围:3.0 V ~ 3.6 V
  • 复位有效电平:低电平有效(Active Low)
  • 输出类型:开漏(需要外接上拉)
  • 复位超时:典型 200 ms(上电或欠压恢复后的复位保持时间)
  • 温度范围:-40 ℃ ~ +125 ℃
  • 额外功能:手动复位输入、看门狗定时器

注:市场资料中该系列可有不同阈值和输出形式变种(如 2.93 V 或推挽输出),具体选型请以器件标识和数据手册为准。

三、功能简介

  • 欠压检测:当 VCC 下降至阈值以下,器件将把 RESET 拉低,保证被监控系统处于复位状态直到电源稳定并达到保持时间。
  • 上电复位(POR):上电时自动产生至少 200 ms 的复位脉冲,确保系统初始化完成。
  • 手动复位(MR):外部低电平触发手动复位,便于系统调试或外部事件干预。
  • 看门狗(WDT):当看门狗脉冲(WDI)未在规定时间内到达时,器件产生复位或看门狗输出以恢复系统。

四、典型应用与连接建议

  • 应用场景:嵌入式主控板、电源管理模块、工业控制、通信设备等需要可靠复位与看门狗功能的场合。
  • 外围建议:由于输出为开漏,RESET 引脚需外接上拉电阻(推荐 10 kΩ);在 VCC 与 GND 之间并联 0.1 μF 陶瓷去耦电容,靠近器件引脚以抑制电源噪声;MR 引脚同样建议上拉至 VCC,便于外部按钮或逻辑控制拉低触发复位。
  • 设计提示:若需更长复位保持时间,可用外部逻辑配合定时电路或选购该系列具有更长延时的变体;推挽输出或不同阈值需求请核对具体型号。

五、封装与可靠性

器件采用 SOT-23-5 小封装,适合密集 PCB 布局与自动贴装。工作温度覆盖工业级范围(-40 ℃ ~ +125 ℃),可满足多数工业与汽车周边电子应用的环境要求。订购型号为 MAX823SEUK+T(卷带/盘装),请确认来源并参考官方数据手册以获取完整电气参数和封装图。

六、选型与注意事项

在最终选型前务必核对数据手册中阈值公差、电源电流、输出漏电流、看门狗定时精度和引脚排列。若系统需与其他电平域接口,注意上拉电阻和容性负载对复位沿的影响。对于关键系统,请做上电与断电瞬态仿真,验证复位行为满足系统启动序列要求。

小结:MAX823SEUK+T 是一款功能完备的单路电压监控与复位管理器件,集上电复位、手动复位与看门狗于一体,适用于需要稳定可靠复位策略的嵌入式系统。实际应用请参照 ADI 官方数据手册并根据系统需求选择合适变体。

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
