CN706R 产品概述

一、概要介绍

CN706R 是 CONSONANCE(上海如韵)推出的一款复位监控芯片(Reset IC),用于为微控制器、数字系统及电源管理电路提供可靠的上电复位、欠压检测及外部手动复位功能。器件工作电压范围为 1.15V 至 5.5V,适应多种单电池与多电压系统。复位为低电平有效,阈值电压为 2.63V,内部集成看门狗定时器,复位保持时间 200ms,静态电流仅 52µA,工作温度范围 -40℃ 至 +85℃,封装为 SOP-8。

二、主要功能与特性

  • 工作电压宽(1.15V ~ 5.5V),兼容 1 节锂电池及常见 3.3V/5V 系统。
  • 欠压监测阈值:2.63V(当 VCC 低于该阈值时,器件输出复位信号)。
  • 复位输出低电平有效,保证系统在电压异常或上电瞬态期间保持复位状态。
  • 手动复位(外部按键)输入,便于人工强制重启或维修时复位设备。
  • 内置看门狗定时器,用于检测系统运行异常并在超时后触发复位。
  • 固定复位超时 200ms(复位释放前保证最小延时),有利于系统稳定上电。
  • 极低静态电流 Iq = 52µA,适合电池供电及低功耗应用。
  • 工业级温度范围 (-40℃ ~ +85℃),适合多种工作环境。
  • 标准 SOP-8 封装,便于批量生产和手工焊接。

三、典型应用场景

  • 单片机/MCU 及数字电路的电源监控与上电复位。
  • 电池供电设备(无线传感器、可穿戴、遥控器等),受益于低静态电流。
  • 工业控制与仪表,要求宽温度和可靠复位。
  • 消费电子、通信终端、智能家居等需要看门狗保护的系统。

四、使用建议与典型连接

  • VCC 旁放置 0.1µF 去耦电容,靠近芯片供电脚以抑制上电杂讯。
  • 手动复位端(若为输入)建议通过 10k 上拉到 VCC,并且按键短接到地,按下时触发低电平复位;可并联一个小电容(例如 10nF)做按键去抖或延时。
  • 若需要比 200ms 更长的保稳定时间,可外加 RC 电路或在软件中延长启动时序。
  • 看门狗功能使用时,确保主控按规范周期喂狗;若需要更复杂策略,可在外部电路中配合监督。
  • 布局注意:复位输出与敏感信号走线尽量短且远离开关电源干扰源,保证稳定检测。

五、选型与注意事项

  • CN706R 的 2.63V 阈值适合 2.7V 附近系统的欠压检测;选择时需确认系统最低工作电压与阈值匹配。
  • 复位超时为固定值 200ms,若系统启动需更长时间则需额外设计延时。
  • 查看具体引脚功能与时序图(建议参阅器件数据手册)以确认复位输出类型(推挽或开路漏极)及手动复位逻辑。
  • 在高噪声环境中,可在复位引脚增加 RC 滤波以防误触发。

六、优势总结

CN706R 以其宽电压范围、低功耗、集成看门狗与手动复位功能为系统提供可靠的电源与运行监控能力。适用于电池供电及工业级应用,是提高系统稳定性与抗故障能力的实用器件选择。若需详细引脚定义、时序波形及典型应用电路,请参考 CONSONANCE 官方数据手册。

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
