CH410K 产品概述

一、产品简介

CH410K 是南京沁恒(WCH)推出的一款单路电压监控器,面向微控制器和数字系统电源看护场景。器件监测单路电源电压,工作电压范围宽(1.0V~5.3V),当被监控电压低于设定阈值时输出复位信号,复位输出保持约20ms,以保证系统可靠复位并完成上电初始化。

二、主要规格

  • 监控路数:1 路
  • 工作电压:1.0V ~ 5.3V
  • 可选阈值:2.3V、3.0V(常见两档)
  • 复位时间(保持时间):约 20 ms
  • 复位有效电平:支持高电平有效与低电平有效两种版本
  • 输出类型:提供推挽(Push‑Pull)与开漏(Open‑Drain)两类输出形式
  • 静态电流(Iq):低功耗版本典型为 800 nA,另有约 1.6 μA 的规格可选
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOT-363(小型封装,适合空间受限应用)

三、功能与优势

  • 宽供电范围,能覆盖从超低压供电到典型 3.3V/5V 系统,适配多种 MCU 与外设。
  • 两档阈值设计便于根据被监控设备的最低工作电压选择合适型号,减少误复位。
  • 低静态电流非常适合电池供电或功耗敏感的终端产品,延长待机时间。
  • 提供推挽和开漏输出,满足主动驱动复位或多点并联(wired‑OR)场合的不同需求。
  • 小封装 SOT-363 节省 PCB 面积,适用于便携与空间受限产品。

四、典型应用

  • 单片机(MCU)系统电源看护与复位管理
  • 电池供电设备与便携式终端(传感器、手持设备)
  • 工业控制与仪表上电监控
  • 网络设备、通信终端的电源完整性防护

五、设计建议

  • 根据 MCU 或数字芯片的最低工作电压选择 2.3V 或 3.0V 阈值,以保证在电压接近临界时能及时复位。
  • 开漏输出版本需在外部增加上拉电阻;若需多点复位连线并联,建议使用开漏以实现共线复位。
  • 推挽输出可直接驱动多数复位输入,但对有多个并联器件时要注意驱动冲突。
  • 为减少瞬态误触发,主供电线路建议使用适当的去耦电容并保证上电斜率符合系统要求;如需延长复位保持时间,可在复位输入侧配合 RC 滤波(视具体应用而定)。
  • 布局时将器件靠近 MCU 的复位脚放置,以减小走线干扰与寄生电阻带来的时序偏差。

六、选型要点

选型时关注阈值(2.3V/3.0V)、输出极性(高有效/低有效)、输出类型(推挽/开漏)以及静态电流等级(800nA / 1.6μA),并结合应用的电源电压、复位极性与功耗预算做综合判断。

CH410K 以其宽工作电压、低功耗和小封装特性,适合对上电复位可靠性和功耗敏感的产品,是嵌入式与便携设备电源管理的实用选择。

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
