CN706T 产品概述

一、简介

CN706T 是 CONSONANCE(上海如韵)推出的一款低功耗电压监控与复位管理芯片,封装为 SOP-8。该器件对电源进行看门与复位监控,支持手动复位、内置看门狗定时器,设计用于对单片机、数字系统和电源管理电路进行可靠的复位控制。工作电压范围广(1.15V ~ 5.5V),尤其适合 3.3V 系统(阈值 3.08V)和电池供电设备。

二、主要特点

  • 工作电压:1.15V ~ 5.5V,适配多种电源轨。
  • 复位有效电平:低电平有效(RESET 为低有效输出)。
  • 电压监测阈值:3.08V(用于 3.3V 系统的欠压检测)。
  • 手动复位:提供外部触发的手动复位功能,便于人工或外部电路干预。
  • 看门狗定时器:内置 watchdog,支持外部喂狗接口,提升系统异常自恢复能力。
  • 复位超时:200 ms(典型),保证电源稳定后 MCU 有充足的上电复位时间。
  • 工作温度范围:-40℃ ~ +85℃,满足工业级应用要求。
  • 静态电流(Iq):52 µA(低功耗),适合电池供电场景。
  • 封装:SOP-8,便于 PCB 布局与手工焊接。

三、功能与应用场景

  • 单片机与微控制器系统的电源欠压检测与上电复位(POR)。
  • 便携式与电池供电设备,对低静态电流的严格要求场合。
  • 工业控制、通信设备和消费电子的可靠复位管理。
  • 电源管理模块、电池保护电路及多电源系统的电压监控与看门狗功能。
  • 系统现场维护时的手动复位、故障恢复与死机自动复位(看门狗)。

四、典型使用建议

  • 电源去耦:在 VCC 与 GND 之间放置 0.1 µF 陶瓷去耦电容,靠近芯片电源引脚,以抑制瞬态噪声。
  • RESET 拉电阻:RESET 为低电平有效,复位释放后应确保外部电路不会强制拉低,必要时在 RESET 引脚加上上拉电阻。
  • 手动复位输入:手动复位按键或外部故障信号应为瞬时低电平脉冲,避免长时间拉低影响系统。
  • 看门狗使用:定期由 MCU 喂狗以避免误复位;喂狗周期应短于看门狗超时但长于系统常规任务时间。
  • 上电与掉电管理:3.08V 阈值适合 3.3V 供电场景,若用于其他电压轨需确认阈值满足系统需求或使用其他型号。

五、优势与注意事项

优势:

  • 宽电压范围与低静态电流,兼顾兼容性与低功耗。
  • 内置看门狗与手动复位,提高系统健壮性和可维护性。
  • 200 ms 的复位超时有利于外设和时钟稳定。

注意事项:

  • 阈值为 3.08V,请在 3.3V 系统中验证阈值容差对上电时序的影响。
  • 在高噪声环境中,注意布线与屏蔽,避免误触发复位。
  • SOP-8 封装需留意焊接温度和散热要求,工作温度为 -40℃ 到 +85℃。

六、封装与订购信息

  • 品牌:CONSONANCE(上海如韵)
  • 型号:CN706T
  • 封装:SOP-8
  • 工作温度:-40℃ ~ +85℃
  • 推荐在 BOM 中标注完整型号与封装以方便采购与替换。

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
