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。
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。
(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。)
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
