SSP61CN1902MR 产品概述

一、概述

SSP61CN1902MR 是上海矽朋(Siproin)推出的一款单路电压检测与复位芯片,封装为常见的 SOT-23 小型封装。器件集成了阈值检测和滞后功能,输出为开漏(Open-drain)型,适用于对单一路电源进行欠压检测、上电复位(POR)与系统看护。其工作电压范围宽、封装小、功耗低,适合便携式与嵌入式系统的电源管理需求。

二、主要参数一览

  • 芯片类型:电压检测器 / 复位监控芯片
  • 输出类型:开漏(需外部上拉)
  • 工作电压范围:0.8 V ~ 5.0 V
  • 检测阈值:1.9 V(阈值电压)
  • 受监控电压通道:1 路
  • 滞后功能:内置滞后以抑制毛刺与抖动
  • 工作温度范围:工业级 -40 ℃ ~ +85 ℃(商业级常见范围 -30 ℃ ~ +80 ℃)
  • 封装:SOT-23(便于贴装与空间受限设计)
  • 品牌:Siproin(上海矽朋)
  • 型号:SSP61CN1902MR

三、功能与工作原理

该器件监测被检测端电压,一旦被监控电压下降到低于1.9 V 的阈值,器件将输出低电平(通过开漏输出下拉到低电平),以通知系统处于欠压状态并触发复位动作;当电压回升并超过阈值加上滞后量时,开漏输出释放(由外部上拉恢复为高电平),允许系统复位结束并恢复正常运行。内置滞后设计可以有效避免因噪声或瞬态振荡导致的误动作。

四、优势与适用场景

  • 低电压支持:0.8 V 起即可工作,适用于低电压电池供电设备与单节锂电池系统。
  • 开漏输出:灵活,可与多种逻辑电平兼容,通过选择合适上拉电阻或连接到外部复位逻辑实现系统集成。
  • 小尺寸封装:SOT-23 有利于节省 PCB 面积并降低成本,适合体积受限的移动终端、智能传感器与物联网节点。
  • 抗抖动设计:滞后功能提高系统稳定性,适合噪声环境或存在电源瞬变的场合。
    典型应用包括单片机/微控制器上电复位、看门狗复位配合、便携式设备电源监控、电池管理与电源序列控制等。

五、典型连接建议

  • VDD 端接被监控电源(或单一被监控点)。
  • RESET/OUT 为开漏输出,需外接上拉电阻到目标逻辑电平(如 3.3 V 或 5 V),上拉阻值根据系统响应与功耗权衡通常取 10 kΩ~100 kΩ。
  • 若需延长复位保持时间,可在 RESET/OUT 与地之间并联小容量电容形成 RC 延时,配合上拉电阻实现上电延时。
  • 布线注意:将电源旁路电容靠近器件 VDD 引脚放置,以减小供电瞬态影响。

六、封装与采购信息

  • 封装形式:SOT-23 小型三引脚封装,支持贴片回流焊工艺。
  • 型号标识:SSP61CN1902MR,品牌为 Siproin(上海矽朋)。
  • 选型时可关注批次一致性与温度等级,若在更严格温度或更高可靠性应用中使用,应与供应商确认详细电气特性曲线与可靠性数据。

总结:SSP61CN1902MR 为一款针对单路电源监控的实用型电压检测器,阈值 1.9 V、宽工作电压 0.8 V~5 V、开漏输出与滞后功能使其在嵌入式与便携式系统的上电复位和欠压保护中表现可靠且易于集成。若需更详细的电气参数、转移特性曲线、温度漂移和典型应用电路图,请参考生产厂商的完整器件数据手册或向供应渠道获取样片测试数据。

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.
