SSP61CN3002MR — 监控与复位电压检测器产品概述

一、产品简介

SSP61CN3002MR 是由 Siproin(上海矽朋)推出的一款小尺寸电压检测与复位芯片,封装为 SOT-23-3。该器件采用开漏(Open‑Drain)输出,针对单路电压监控与系统复位需求设计,适用于低功耗、嵌入式与电池供电设备。典型应用包括微控制器上电复位、欠压检测(BOD)、电源管理与系统看门狗前端等场景。

二、主要特点

  • 输出类型:开漏(Open‑Drain),便于与外部上拉电阻或共享总线配合使用。
  • 静态电流(Iq):典型 900 nA,适合超低功耗应用,减少待机能耗。
  • 阈值电压:3.0 V(检测阈值),用于判断供电是否达标。
  • 工作电压范围:0.7 V ~ 10 V,覆盖常见单节锂电、3.3 V/5 V 系统及更宽电源场景。
  • 监控通道数:1 路,专注单点电压检测与复位。
  • 工作温度范围:-30 ℃ ~ +80 ℃,满足多数工业级或消费类应用环境。
  • 封装:SOT-23-3,体积小,便于表面贴装与空间受限的电路板设计。
  • 品牌:Siproin(上海矽朋),支持产线与渠道采购。

三、电气性能概览(要点)

  • 检测阈值:3.0 V(适用于 3.3 V 系统的电压缺失检测);实际产品应参考规格书确定公差与温漂。
  • 静态电流:900 nA(典型值),有利于延长电池供电产品的待机寿命。
  • 开漏输出:需要外部上拉电阻连接至目标逻辑电平(如 VCC 或 MCU 输入电压);在检测到欠压时输出被拉低以产生复位信号。
  • 供电范围:0.7 V 至 10 V,器件能在较宽电源条件下稳定工作,但不同阈值或功能可能只在一定电压区间内有效,设计时请参阅完整数据手册以确认各项极限与工作条件。

四、引脚与封装说明

  • 封装:SOT-23-3(三引脚小封装),便于批量贴装与自动化组装。
  • 常见引脚分配(设计一般约定,具体引脚名称与管脚功能请以数据手册为准):
    • VCC:供电输入。
    • GND:接地。
    • OUT:开漏复位输出(需上拉电阻)。
  • 布局建议:将 VCC 与 GND 的引脚附近放置去耦电容,输出引脚走线尽量短且靠近 MCU 复位输入,以减小杂散耦合与噪声干扰。

五、典型应用场景

  • 单片机/微控制器的上电/欠压复位(BOD)。
  • 电池供电终端(如便携设备、传感器节点)的欠压保护与电源监控。
  • 多电源系统的电源序列控制与复位链路。
  • 工业控制与通信设备中对关键电压轨的检测与安全复位。
  • 任何需低静态电流且要求可靠复位信号的嵌入式系统。

六、设计与使用注意事项

  • 上拉电阻:由于输出为开漏结构,必须配合上拉电阻使用;常用值为 10 kΩ 左右,具体值视速度与功耗权衡而定。
  • 输出极性:此类电压检测器通常在被监控电压低于阈值时将 OUT 拉低,产生“低电平有效”的复位信号;系统中 MCU 复位输入的极性应与之匹配。
  • 去耦电容:建议在 VCC 与 GND 之间放置 0.01 μF~0.1 μF 的去耦电容,靠近器件封装放置。
  • 温度与容差:产品给出的阈值在不同温度下有一定漂移,设计时应预留一定裕量并参照器件数据手册中的温度系数与容差项。
  • 多器件并联:若需实现多点复位或总线共享,请注意开漏输出的并联行为是“与”逻辑(wired‑AND),拉低任一输出会使线被拉低。

七、订购与替代建议

  • 型号:SSP61CN3002MR,封装 SOT-23-3,品牌 Siproin(上海矽朋)。
  • 采购时请核对完整规格书以确认阈值公差、复位延时(若有)、引脚定义与可靠性参数。
  • 若需其他阈值(如 2.5 V、4.5 V)或不同封装/工作温度范围,可在同类电压检测器产品线中查找对应型号作为替代。

总结:SSP61CN3002MR 以其 3.0 V 阈值、开漏输出、超低静态电流和宽工作电压范围,适合对功耗敏感且需要可靠复位的嵌入式与电池供电应用。在实际设计中,请结合完整数据手册完成元件选型和 PCB 布局,以保证系统稳定性与可靠性。

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.
