MAX6301ESA+T 产品概述

一、产品简介

MAX6301ESA+T 是一款面向微处理器/微控制器电源监控的电压监视器,适用于 1.0V 至 5.5V 的单电源系统。器件集成了欠压复位(Watchdog)、手动复位输入和低电流待机特性,复位输出为漏极开路(open-drain)、低电平有效,复位保持时间约为 4 ms,典型应用于便携式和低功耗嵌入式系统。封装为 SO-8(NSOIC-8),温度等级为 -40℃ 至 +85℃(Ta)。

二、主要特性

  • 电源工作范围:1.0 V ~ 5.5 V
  • 监测阈值:1.24 V(典型)
  • 输出类型:漏极开路(Open-drain),低电平有效复位
  • 复位保持时间:4 ms(触发后复位最低持续时间)
  • 看门狗定时器:内置(需外部喂狗信号以避免看门狗复位)
  • 手动复位:外部 MR(Manual Reset)引脚,可强制产生复位
  • 工作温度:-40℃ ~ +85℃(Ta)
  • 静态电流(Iq):约 7 μA(低功耗,适合电池供电系统)
  • 封装:SO-8(NSOIC-8)
  • 品牌归属:ADI(含原 Linear/Maxim 系列器件家族)

三、功能说明

  • 欠压监测:当 VCC 低于内部比较器阈值(1.24V)时,器件触发复位输出为低电平,直到电源恢复并稳定超过阈值与滞后区间后延时释放复位。
  • 漏极开路输出:复位输出为开漏结构,需要外部上拉电阻(推荐 10 kΩ 至 VCC)连接到被监控的数字电路复位端。开漏输出便于与不同电压域的系统兼容。
  • 手动复位:通过 MR 引脚施加低电平可立即触发复位,松开后保持至少 4 ms 以保证系统可靠复位(外部 RC 可延长复位时间)。
  • 看门狗功能:器件提供看门狗监控,若主控未在规定周期内喂狗,则看门狗将产生低电平复位,促使系统复位并尝试恢复。复位持续时间同样由器件内部定时逻辑保证约 4 ms。

四、典型应用与设计建议

  • 应用场景:微控制器/微处理器上电复位、电源监控、看门狗保护、手动复位按钮、便携式与电池供电设备、工业控制和通信终端等。
  • 电路建议:复位输出接到 MCU RESET 并通过 10 kΩ 上拉到 VCC;MR 与一个去抖电路(如 0.01 μF 到地)或外部按钮并联使用以保证人为复位的可靠性;若需延长复位时间,可在 MR 或 RESET 总线上加一个小电容形成 RC 延时。
  • 低功耗考虑:静态电流仅 7 μA,适合待机/睡眠场景,但若系统对上电侦测和看门狗有严格时序要求,应在 PCB 布局上注意 VCC 去耦与电源上升时间,以免误触发复位。

五、封装与订购信息

  • 封装:SO-8(NSOIC-8)适用于常规 SMT 装配。
  • 常用订购型号示例:MAX6301ESA+T(请依据供应链与现货情况确认厂家编码及替代型号)。购买时请注意器件生产商、版本与温度等级,确保与设计规范一致。

六、优势与注意事项

  • 优势:宽工作电压、极低静态电流、集成看门狗与手动复位、漏极开路输出便于系统集成。
  • 注意事项:输出为开漏需上拉;看门狗喂狗时序需参考具体数据手册(不同厂商实现细节可能略有差异);在电源瞬态或噪声环境下建议增加去耦,以避免误复位。

如需更精确的时序、看门狗周期、阈值公差与电气特性,请参考器件完整数据手册或向供应商索取参数表以进行最终硬件验证。

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
