SGM809-ZXN3/TR 产品概述

一、概述

SGM809-ZXN3/TR 是由圣邦微(SGMICRO)推出的一款单路电压监控器(复位 IC),采用 SOT-23 小封装并以带卷装(TR)方式供货。器件用于对系统供电电压进行实时监测,在监控电压异常时产生复位信号,保证微控制器和数字逻辑在电源不稳时不会进入不可预测状态。器件工作温度范围宽(-40℃ 至 +125℃,Tj),适合工业级应用。

二、主要特性

  • 工作电压:1.2 V ~ 5.5 V
  • 监控通道:1 路
  • 阈值电压:2.32 V(监测阈值)
  • 复位有效电平:高电平有效(RESET = 高表示复位)
  • 输出类型:推挽输出(Push-Pull)
  • 复位超时:240 ms(电压回到阈值以上后保持复位时间)
  • 无手动复位按键输入、无看门狗定时器功能
  • 封装:SOT-23(带卷装/TR)
  • 工作温度:-40℃ ~ +125℃(Tj)

三、工作原理与典型行为

当被监控电压下降至低于 2.32 V 时,器件将把复位输出拉至高电平,向系统发出复位请求;当电压回升超过阈值后,器件在内部定时 240 ms 后释放复位(复位输出返回低电平),为电源和时钟稳定提供缓冲时间。推挽输出能直接驱动后级复位引脚或外部指示器,无需上拉电阻。

四、封装与可靠性

SOT-23 小尺寸封装便于在空间受限的板级设计中应用,TR(带卷装)适合自动化贴片生产。-40℃ 至 +125℃ 的工作温度范围满足多数工业与汽车电子周围环境要求(请参考数据手册以确认具体的热性能与焊接规范)。

五、典型应用

  • 微控制器与数字电路复位保护
  • 电池供电与便携设备的电源管理
  • 工业控制与传感器节点电源监控
  • 电源上电排序与系统看门(作为简单复位方案)
  • 消费类电子产品的电压故障保护

六、设计建议

  • 将 VCC 与监控节点靠近器件供电引脚并加去耦电容以抑制瞬态干扰。
  • 由于输出为推挽型,直接驱动目标复位引脚或指示器无需外部上拉,但若系统需要开漏特性可在外部增加器件实现。
  • 若需手动复位或看门狗功能,可外接简单按键电路或选用带相应功能的监控器件替代。

总结:SGM809-ZXN3/TR 提供稳定的单电压监控与 240 ms 复位保持时间,封装小、温度范围宽,适合对系统可靠性有严格要求的各种电子设备。欲获取更详细的电气参数、引脚定义和典型应用电路,请参考厂商完整数据手册。

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
