MCP120T-270I/TT 产品概述

一、概述

MCP120T-270I/TT 是 MICROCHIP(美国微芯)推出的一款单通道电压监控器,采用 SOT-23-3 封装,面向需可靠上电复位的低功耗系统。器件提供开漏输出(或称开路集电极),复位为低电平有效,适用于工业温度范围(-40℃ ~ +85℃)。该器件设计简单、稳定,便于与微控制器、电源管理电路配合使用。

二、主要电气特性

  • 工作电压范围:1.0 V ~ 5.5 V,覆盖常见单节锂电、3.3V 与 5V 系统。
  • 阈值电压:2.925 V(器件工作点,当监控电压低于该阈值时触发复位)。
  • 复位超时(复位脉冲宽度):约 350 ms,保证系统在电源达到稳定后有足够时间完成初始化。
  • 静态电流(Iq):45 μA,适合电池供电或低功耗应用。
  • 输出类型:开漏(需外部上拉电阻);复位有效电平为低电平。
  • 监控通道数:1 通道。
  • 无看门狗功能、无手动复位引脚(复位由监控电压自动产生)。

三、功能与应用场景

MCP120T-270I/TT 主要用于监控单一路电源并在电压异常时生成复位信号,典型应用包括:

  • MCU、电源管理 IC 的上电复位与电压监测;
  • 电池供电设备的欠压保护与恢复控制;
  • 工业控制与仪器仪表的可靠上电与掉电保护;
  • 需要低静态电流和小封装的便携电子设备。

四、使用要点与设计建议

  • 因为输出为开漏结构,必须在系统中外接上拉电阻(典型值 10 kΩ 可作为起始参考),上拉电压可接至系统 VCC 或其他合适电源。
  • 复位为低电平有效:当被监控电压低于 2.925 V 时,复位输出被拉低;电压恢复并超过阈值后,等待复位超时约 350 ms 后释放复位(高阻态)。
  • 器件无看门狗或手动复位输入,若需要这类功能,应在系统中通过 MCU 或外部电路补充。
  • SOT-23-3 小封装利于空间受限的 PCB 布局,但注意热量与接地良好设计以保证温度与稳定性。

五、封装与型号说明

  • 封装:SOT-23-3,适合常见贴片工艺与批量生产。
  • 型号后缀 I 表示工业温度等级(-40℃ ~ +85℃)。MICROCHIP 的该系列以稳定的工艺和长期可用性著称,便于长期设计锁定。

总体而言,MCP120T-270I/TT 是一款结构简单、功耗低且可靠的单通道电压监控器,适合要求稳定上电复位和空间受限的嵌入式与电源管理应用。

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
