SSP61CN4802MR 产品概述

SSP61CN4802MR 是上海矽朋(Siproin)推出的一款单电压监控与复位芯片,采用 SOT-23 小型封装,面向对系统电源完整性有严格要求的嵌入式与工业应用。器件提供开漏(Open-Drain)复位输出、低电平有效的复位信号以及宽工作电压范围,适合多种供电环境下的上电复位和欠压保护。

一、主要特性

  • 输出类型:开漏 (Open-Drain),方便与不同电平的外部电路连接。
  • 复位有效电平:低电平有效(当监控电压低于阈值时,RESET 拉低)。
  • 监控数量:单路电压监控。
  • 阈值电压:4.8V(检测阈值,低于该电压时触发复位)。
  • 工作电压范围:约 0.7V 至 8V,适配低压及常见单电源系统。
  • 看门狗:无(仅提供电压监控与复位功能,无看门狗计时器)。
  • 工作温度范围:-30°C ~ +80°C。
  • 封装:SOT-23,体积小,适合空间受限设计。

二、功能说明

SSP61CN4802MR 对外部被监控电源进行比较,当被监控电压下降并穿越 4.8V 阈值时,器件将把复位输出拉至低电平,从而对微控制器或数字逻辑进行复位或阻止误动作。由于采用开漏输出,片上不会主动拉高输出,需要外部上拉电阻或与系统总线共同上拉到所需逻辑电平。

器件不包含看门狗功能,仅作为电源监控与复位源使用,适合与 MCU 的片内看门狗或其它外部监控电路配合使用。

三、电气参数要点

  • 检测阈值:4.8V(主要参考值,精度详见规格书)。
  • 供电与监控:器件在 0.7V 至 8V 范围内工作,但当系统工作在接近阈值附近时,应关注器件在低电压下的行为与响应能力。
  • 输出形式:开漏输出,需外部上拉电阻(典型取值范围 10kΩ~100kΩ,具体依系统上拉电源与响应速度要求选择)。
  • 温度性能:器件额定工作温度 -30°C~+80°C,满足多数工业与消费类应用的温度需求。

(注:以上为关键特性摘要,具体电流消耗、阈值公差、迟滞、响应时间等详细电气指标请以厂方最新版数据手册为准。)

四、封装与引脚说明

SSP61CN4802MR 提供 SOT-23 小型封装,便于表面贴装与自动化生产。典型引脚配置包含 Vcc(供电/被监控引脚)、GND(地)、RESET(开漏输出)。SOT-23 尺寸有利于空间受限、成本敏感的款型。

五、典型应用场景

  • 单电源微控制器系统的上电复位与欠压保护。
  • 工业控制、仪表、通讯设备中的电源监控。
  • 电池供电设备的电压监测与复位管理。
  • 各类需要可靠复位信号但对封装和成本有要求的嵌入式终端。

六、使用建议与注意事项

  • 由于输出为开漏,设计时应配置合适的上拉电阻并确认上拉电压不超过器件允许的最大电压。
  • 在阈值附近可能发生抖动,建议在系统设计中考虑外部滤波或使用上拉电阻与电源去耦电容来降低噪声影响。
  • 器件无看门狗功能,若需运行期复位或死机检测,请搭配 MCU 内部或外部看门狗方案。
  • 在低温或高温极端环境下,关注复位阈值随温度的漂移,必要时参照数据手册进行温度补偿设计。

七、可靠性与环境适应性

SSP61CN4802MR 的工作温度范围覆盖 -30°C 至 +80°C,适用于大多数室内、工业和便携式应用。由于采用 SOT-23 小封装,建议在 PCB 设计与焊接工艺中遵循厂方焊接与回流规范,以保证长期可靠性。具体的老化、ESD、机械应力等可靠性测试指标请参考厂方提供的认证与试验报告。

总结:SSP61CN4802MR 是一款针对单电源监控场景设计的简洁可靠的复位监测器,具备开漏输出、4.8V 阈值及宽工作电压和温度范围,适合对电源完整性要求较高但不需要看门狗功能的各类电子系统。如需详细电气特性与引脚排列,请参照上海矽朋官方数据手册或联系供应商获取最新技术支持。

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
