SGM811-TXKA4/TR 产品概述
SGM811-TXKA4/TR 是一款由圣邦微（SGMICRO）推出的高性能监控和复位芯片，专为各种电子设备提供有效的电压监测和复位解决方案。该芯片采用 SOT-143 封装，体积小巧，适合广泛的应用场景，如电源监控、便携式设备、工业控制等。其主要功能是实时监测电路中的电源电压，当电压低于设定阈值时，芯片会立即驱动复位信号输出，以保证系统的稳定性和可靠性。
主要功能
低电压监测: SGM811 具有 3.08V 的电压检测阈值，主要用于监控包括 LDO 和开关电源在内的电源系统。当输入电压降至 3.08V 以下时，芯片输出低电平信号，表示系统处于不安全状态，促使系统进入复位模式。
复位功能: 在输入电压正常恢复至 3.08V 以上时，SGM811 将释放复位信号，系统可以安全恢复操作。这一机制确保了在电源波动或短时间掉电后，系统不会出现错误状态，增强了设备的抗干扰能力。
低功耗设计: SGM811 采用现代 CMOS 工艺，提供超低的静态功耗，适合电池供电的移动设备，有效延长了设备的使用寿命。
低电平有效: 芯片设计为低电平有效（Active Low），这一设计在许多电子系统中得到了广泛应用，当检测到电压异常时，立即输出一个低电平信号，便于简单快速的复位控制。
应用场景
SGM811-TXKA4/TR 广泛适用于以下场景：
- 消费电子: 如智能手机、平板电脑、家用电器等，能有效防止因电压不稳导致的系统崩溃。
- 工业控制: 在工业控制系统中，保证各种传感器、执行器的电源稳定，避免由于电源问题造成设备故障。
- 便携式设备: 在便携式医疗设备、移动通信设备等对电池寿命要求高的场合，低功耗特性使其成为理想选择。
- 汽车电子: 在车载电子系统中，SGM811 提供电源稳定性监控，为汽车安全提供保障。
技术规格
- 封装类型: SOT-143，适合高密度板上布局。
- 工作电压范围: 适应各种电源供电场景，大多数设备在这一电压范围下都能完美运作。
- 复位延迟时间: 可根据不同应用需求进行定制，确保各类设备在复位和启动时的稳定性。
总结
SGM811-TXKA4/TR 是一款高效、可靠的电压监测与复位芯片，凭借其优异的性能和多样的应用场景，成为现代电子产品中不可或缺的组件。无论是在消费电子、工业控制还是汽车电子领域，SGM811 的低电压检测与复位功能都能提供良好的电源管理解决方案。通过确保系统在电压波动或突发故障情况下的稳定运行，SGM811 为设备的安全性和可靠性提供了强有力的支持。

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.
