SGM897AXUDL6G/TR 产品概述
一、产品简介
SGM897AXUDL6G/TR 为圣邦微（SGMICRO）推出的一款电压监控（复位）芯片，面向对电源异常、上电复位与瞬态缺陷需要快速响应的系统。器件工作电压范围宽（1.6V～5.5V），采用小型 UTDFN-6AL 封装，适合空间受限的便携与嵌入式应用。
二、主要规格
- 芯片类型：电压监控器（复位 IC）
- 工作电压：1.6V ～ 5.5V
- 受监控电压数量：1 路
- 阈值电压：500 mV（标称）
- 输出类型：开漏（open-drain）
- 复位有效电平：低电平有效
- 复位超时：48 μs（上电/复位保持时间）
- 手动复位：无
- 看门狗：无
- 工作温度：-40℃ ～ +125℃（Tj）
三、功能特性
SGM897AX 提供单通道电压监控与自动复位功能：当被监控电压降至门限以下时，器件将输出低电平复位（开漏输出需外接上拉电阻）；被监控电压恢复并稳定超过阈值后，芯片在内置的复位超时（48 μs）后释放复位。这种快速响应适合保护微处理器、逻辑电路在瞬态掉电或电源翻转时避免异常工作。
四、典型应用场景
- 微控制器与数字 IC 的上电复位监控
- 电池供电与便携设备的电源监督
- 电源管理与电压检测模块
- 工业与汽车电子（在符合温度等级下）中的电源可靠性提升
五、封装与电路注意事项
SGM897AX 提供 UTDFN-6AL 小尺寸封装，利于高密度板设计。由于输出为开漏结构，设计时需外接合适的上拉电阻（典型值可取 10 kΩ 量级，视系统速度与功耗权衡）。建议在电源引脚附近配置去耦电容，布线短且尽量靠近芯片以保证复位门限检测的稳定性；复位线应避免长线或高噪声环境直接连接，以减少误复位风险。
六、设计建议
- 根据系统工作电压选择合适的上拉电阻与滤波策略；
- 在高噪声环境下，可在复位输入/监控引脚加入小电容做滤波；
- 若用于关键安全系统，建议配合电源监督与冗余策略共同使用。
SGM897AX 以其宽工作电压、快速复位响应与小封装，适合对上电与瞬态保护有苛刻要求的现代电子系统。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
