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。
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。
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。

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.
