SGM804-2.63YN5G/TR 产品概述

一、概述

SGM804-2.63YN5G/TR 是 SGMICRO(圣邦微)推出的一款低电压监控复位芯片,采用 SOT-23-5 封装,适用于各种微控制器和系统电源监督场景。器件监控单路电压,当被监控电压低于阈值时输出主动复位信号;器件工作电压范围宽(1.0 V 至 5.5 V),适配电池供电与常见单电源系统。该型号阈值电压为 2.63 V,复位为低电平有效,复位脉冲最短保证时间为 4.25 ms。

二、主要特点

  • 芯片类型:电压监控器(复位 IC)
  • 监控通道:单路电压监测
  • 工作电压范围:1.0 V ~ 5.5 V,支持低压系统
  • 阈值电压:2.63 V(固定)
  • 复位有效电平:低电平有效(RESET 为逻辑低表示复位)
  • 输出类型:推挽输出(能驱动高、低电平)
  • 复位超时(复位脉冲宽度保证):4.25 ms
  • 无手动复位输入、无看门狗定时器功能
  • 工作温度范围:-40 ℃ ~ +85 ℃(Ta)
  • 封装:SOT-23-5,适合体积受限应用

三、功能与工作行为

当被监控的 VCC(或指定电源轨)低于 2.63 V 时,SGM804-2.63YN5G/TR 会将 RESET 输出拉为低电平,向系统发出复位请求,保证系统处于已知初始状态;当电压回升到阈值之上并稳定后,器件继续保持 RESET 低电平至少 4.25 ms(复位超时),随后释放复位(RESET 回到高电平),确保上电/掉电切换期间系统完成初始化。推挽输出可直接驱动多数 MCU 的复位引脚,无需外部上拉电阻(但应参考系统电平与负载能力)。

四、典型应用

  • 单片机、DSP、FPGA 等数字系统的电源监控与上电复位
  • 电池供电设备、电源管理模块
  • 工业控制、通信终端、消费电子的可靠复位设计
  • 数据采集与测量仪器,避免低压造成的运行异常

五、设计与布局建议

  • 将 SGM804 放置靠近被监控电源源头和 MCU 的复位引脚,减小走线寄生与干扰。
  • 在芯片 VCC 端推荐放置 0.1 μF 陶瓷去耦电容,以抑制瞬态噪声,保证阈值检测稳定。
  • 复位线尽量短且远离高电流/高频信号线,必要时在 RESET 与 MCU 之间加 RC 滤波以滤除瞬态脉冲。
  • 由于器件不具备手动复位引脚,若系统需要外部按键复位功能,可在 RESET 与按键间采用开关逻辑或外部门控电路实现。

六、封装与环境指标

SGM804-2.63YN5G/TR 提供 SOT-23-5 小封装,适合空间受限的便携与嵌入式设备。器件在 -40 ℃ 到 +85 ℃ 的温度范围内工作,满足大多数工业级与商业级应用的环境要求。

小结:SGM804-2.63YN5G/TR 以其宽工作电压、固定 2.63 V 阈值和推挽输出特性,为需要可靠上电/欠压复位且体积受限的系统提供了简洁有效的电压监控解决方案。

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
