CN825S 产品概述

一、概述

CN825S 是由 CONSONANCE(上海如韵)推出的一款单路电源监控与复位管理芯片,采用 SOT-23-6 小封装,专为对 MCU / DSP / FPGA 等数字系统提供可靠上电复位(POR)、掉电检测(BOD)和系统看门狗功能而设计。器件工作电压范围宽(1.1V–6.5V),静态电流极低,适合电池供电与低功耗应用,并满足工业级温度要求。

二、主要规格(关键参数)

  • 芯片类型:电源监控器(单路受监控电压)
  • 受监控电压数:1
  • 阈值电压(典型):2.93 V
  • 复位超时(脉冲保持时间):约 200 ms
  • 复位有效电平:提供低电平有效与高电平有效输出选项
  • 看门狗定时器:有(用于检测软件死锁并触发复位)
  • 手动复位:支持外部手动复位输入
  • 工作电压范围:1.1 V ~ 6.5 V
  • 静态电流(Iq):约 16 μA
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOT-23-6
  • 品牌:CONSONANCE(上海如韵)

三、功能亮点与优势

  • 低功耗:16 μA 的静态电流非常适合对耗电敏感的便携式或长期待机设备。
  • 宽电压范围:1.1 V 至 6.5 V 支持多种电源体系(单节锂电、两节电池并联或较高系统电压)。
  • 稳健的复位保证:2.93 V 阈值配合 200 ms 的复位延时,能有效避免上电毛刺或瞬态下降导致的系统误动作,确保 MCU 在稳定电压下启动。
  • 看门狗与手动复位:集成硬件看门狗用于软件异常恢复,手动复位输入便于调试与人为复位操作。
  • 小尺寸封装:SOT-23-6 有利于空间受限的 PCB 布局与自动化贴片生产。

四、典型应用场景

  • 电池供电的智能终端、便携式仪器、遥测设备
  • 工业控制与嵌入式控制器(要求宽温、可靠复位)
  • 物联网节点与无线传感器,要求低功耗待机与可靠启动
  • 汽车电子的辅助电源监控(在满足温度及车规要求的前提下)

五、使用建议与注意事项

  • 布局:CN825S 建议靠近被监控的 VCC 引脚放置,且 VCC 与 GND 之间应加 0.1 μF 陶瓷旁路电容以抑制瞬态噪声。
  • 阈值与容差:设计时应考虑阈值公差与温漂(参考芯片数据手册),必要时在系统上采取合适的电压裕度。
  • 复位脉冲:200 ms 的复位超时适合大多数 MCU 启动序列;若系统需要更长的上电迟滞,请在系统层面设计延时或外部复位扩展电路。
  • 看门狗配置:正确设置看门狗喂狗周期,避免误触发重启;在进入长时间阻塞(如固件升级)前需先禁用或延长看门狗超时。
  • 选型确认:产品在不同出厂选项上可能提供低电平有效或高电平有效的复位输出,请在采购时确认所需的输出极性和引脚定义,详细管脚与电气特性请参照官方数据手册。

六、封装与订购信息

  • 型号:CN825S
  • 封装:SOT-23-6
  • 生产商:CONSONANCE(上海如韵)
  • 购买时请核对完整型号、封装与复位极性选项,并以官方提供的数据手册为准以获得详细的引脚排列、电气参数和应用电路示例。

如需更详细的电气特性、引脚定义、典型应用电路或参考 PCB 布局指导,请提供是否需要数据手册或具体的应用场景,我可以进一步帮助提炼设计注意点与示意电路。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
