SGM811-SXKA4/TR 产品概述
一、产品简介
SGM811-SXKA4/TR 是由深圳市圣邦微电子有限公司（SGMICRO）研发的一款监控和复位芯片，特别设计用于低电压监控应用。芯片采用 SOT-143 封装，具有紧凑的体积和高效的性能，适合广泛的电子设备和系统中使用。
二、产品特点
低电平有效：SGM811 的复位信号为低电平有效，即在监测电源电压低于设定阈值时，输出复位信号。这种特性使得它在系统上电时能够提供可靠的复位功能，保护后续电路的稳定性。
阈值电压：该设备具有 2.93V 的监视器电路阈值设计，这意味着在电源电压下降至此阈值以下时，SGM811 会触发复位状态，确保系统能在电压不稳定时保持安全运行。
简单易用：SGM811 的设计考虑了简单易用性。它的布局和连接方式使得工程师在设计电路时能够方便地集成到不同的系统中。
电源电压范围：该芯片能够在广泛的电源电压范围内稳定工作，其工作电压通常在 1.8V 至 5.0V 之间，适用于多种低电压电子设备。
低功耗设计：SGM811 的设计注重能效，在不影响性能的前提下，保持较低的静态电流，这是其适合便携式电源和电池供电设备的核心优势。
三、应用场景
SGM811-SXKA4/TR 芯片的广泛应用场景使其成为电子设计中的理想选择，其适用领域包括但不限于：
便携式电子设备：如移动电话、平板电脑和便携式游戏机等。因其低功耗特性，能够延长电池使用寿命。
工业自动化：在工业控制系统及自动化设备中，SGM811 能够监控电源状态，确保设备在异常电压情况下自动重启，减少设备故障对生产的影响。
消费电子产品：例如家用电器、智能家居设备等，确保在情况不稳定时对电子设备进行复位。
汽车电子：在汽车电子控制单元中用以确保电源电压正常，保障电子系统安全运行。
四、技术参数
- 工作电压范围：1.8V 到 5.0V
- 复位电压阈值：2.93V
- 电源电流：< 1µA（待机状态）
- 输出类型：开路集电极
- 封装形式：SOT-143
五、总结
总的来说，SGM811-SXKA4/TR 监控和复位芯片凭借其低电平有效、精确的阈值电压和低功耗特性，成为了监控和复位应用中的佼佼者。无论是在便携式设备还是工业控制系统中，SGM811 都能提供可靠的电源监控与复位解决方案，帮助设计人员开发出更为稳定和安全的电子产品，进一步推动电子技术的进步与发展。

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.
