MIC6315-29D3UY-TR 产品概述
一、产品简介
MIC6315-29D3UY-TR 是 Microchip（美国微芯）推出的一款低功耗电压监控器（复位监控器），采用 SOT-143-4 小封装，针对单路电源监控设计。器件工作电压范围宽（1.0V～5.5V），阈值电压为 2.93V，复位为低电平有效，适用于对微控制器和数字系统的可靠上电/欠压保护。
二、主要特性
- 监控通道：1 路被监控电压输入。
- 输出类型：开漏输出（需外接上拉电阻）。
- 复位有效电平：低电平有效（Active–Low RESET）。
- 手动复位：具备手动复位（MR），按下可强制产生复位。
- 复位超时：典型 140 ms（在检测到欠压或手动复位释放后保持复位时间）。
- 无看门狗定时器功能。
- 工作电流（静态）：典型 5 μA，适合电池供电或低功耗系统。
- 工作温度：-40℃ 至 +85℃（Ta）。
三、封装与订货信息
封装：SOT-143-4（微小表贴封装，适合空间受限应用）。
型号后缀 “-TR” 表示卷带盘装（Tape & Reel），适合自动贴片生产线。
四、典型连接与使用建议
- 由于输出为开漏结构，需在 RESET 引脚外接上拉电阻到 VDD，常用值 10 kΩ 左右，可根据系统上拉能力与上升时间要求调整。
- 建议在 VDD 引脚附近放置 0.1 μF 陶瓷旁路电容，以抑制瞬态噪声和避免误触发。
- 手动复位（MR）引脚通常接到外部按键或 MCU 调试点，按键闭合时将 MR 拉低即可立即触发复位。
- 复位脉宽由内部定时器（约 140 ms）保证，确保 MCU 在上电或欠压恢复时完成初始化。
五、适用场景
适合各种需要可靠电源监控和上电复位的应用，如便携式电子设备、物联网终端、传感器节点、消费电子、工业控制模块和电池供电系统等。特别适用于对静态电流和封装尺寸有严格要求的场合。
六、设计注意事项
- 在存在高频干扰或大电流突变的系统中，应注意监控端噪声抑制，必要时加滤波电容或阻容滤波。
- 若系统需要推挽复位输出或更高速的响应，可在外部电路中结合缓冲器或比较器实现。
- 请参考 Microchip 官方数据手册获取详细电气特性、典型特性曲线和推荐 PCB 布局指导，以确保性能和可靠性。
总结：MIC6315-29D3UY-TR 提供了简洁可靠的单路电压监控与低电平有效复位功能，低静态电流与小封装使其非常适合节能型和空间受限的嵌入式系统。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
