SGM897AXTN6G/TR 产品概述

一、产品简介

SGM897AXTN6G/TR 是圣邦微(SGMICRO)推出的一款低电压监控与复位管理芯片,用于对单路监控电压进行实时监测并在电压异常时产生复位信号。器件工作电压范围宽(1.6V~5.5V),阈值电压典型值为500mV,复位保持时间(复位超时)约为48μs,输出为开漏结构,封装为 TSOT-23-6,工作结温范围为 -40℃ 至 +125℃。

二、主要特性

  • 芯片类型:电压监控器 / 复位管理器
  • 受监控电压数:1 路
  • 工作电压:1.6V ~ 5.5V(适配低压与常见单节/多节电池、电源轨)
  • 阈值电压:500mV(典型值)
  • 输出类型:开漏(需外部上拉)
  • 复位超时:约 48μs(短时复位保持)
  • 无手动复位按钮引脚、无看门狗功能
  • 工作温度:-40℃ ~ +125℃(Tj),适合工业级温度应用
  • 封装:TSOT-23-6,适合紧凑 PCB 布局

三、典型连接与设计要点

  • 输出为开漏结构,必须在复位输出端(RST)接上拉电阻至目标电平(常接至 VCC 或 MCU 供电电压),上拉电阻典型值 10kΩ,可根据上拉速度与功耗权衡调整。
  • 芯片需靠近 MCU 或受保护模块放置,VCC 引脚旁应放置去耦电容(例如 0.1μF)以保证电源瞬态稳定。
  • 复位保持时间为 48μs,若系统上电或电源恢复需要更长的复位时间,应在复位线上采用外部 RC 延时或使用专用延时器电路进行延长。
  • 由于无手动复位引脚,若需实现按键复位,可用按键短接开路器件或外置晶体管将开漏输出拉低实现手动复位功能。

四、应用场景

  • 单片机(MCU)与DSP的复位监控
  • 可穿戴与便携式电池供电设备
  • 工业控制与仪表(宽温度要求场合)
  • 存储设备、电源管理单元与通信终端的电源完整性保护

五、封装与订购信息

  • 品牌:SGMICRO(圣邦微)
  • 型号:SGM897AXTN6G/TR
  • 封装:TSOT-23-6,适合小尺寸、高密度 PCB 布局
  • 订购时请确认包装选项与批次信息以满足生产需求

六、可靠性与注意事项

  • 器件工作结温范围为 -40℃ 至 +125℃,但在设计中仍需注意功耗与散热条件,避免长时间高温运行导致寿命下降。
  • 使用开漏输出时,复位总线可与多路器件并联实现线与(wired-OR)功能,但并联时需确保上拉电平与各器件兼容。
  • 在关键系统上电顺序、复位时序要求严格的场合,建议进行系统级验证,必要时配合外部延时或上电监控电路使用,以确保可靠复位。

综上,SGM897AXTN6G/TR 提供了一个简单、可靠且适用于宽电压与宽温度范围的单路电压监控解决方案,适合对体积、成本及基础复位功能有要求的各类电子设备。

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
