ETA5001S2D 产品概述
一、产品简介
ETA5001S2D 是钰泰（ETA）推出的一款低功耗电源监测器/电压检测模块，工作电压范围为 3.0V ～ 5.5V，静态电流仅 10μA，工作温度范围 -40℃ ～ +85℃，封装为常见的 SOT-23-3。该器件专为对供电电压进行可靠监测、产生复位或告警信号的便携与低功耗系统设计，适合电池供电与功耗敏感的应用场景。
二、主要特性
- 宽工作电压：3.0V ~ 5.5V，兼容 3.3V 与 5V 系统。
- 极低静态电流：Iq = 10μA，适合长时间待机或电池供电设备。
- 宽工作温度：-40℃ ～ +85℃，满足工业级温度要求。
- 小尺寸封装：SOT-23-3，便于空间受限的 PCB 布局与自动贴片生产。
- 针对电源上电/断电顺序与欠压保护等场景，可与微控制器或电源管理单元配合使用，提高系统可靠性。
三、典型应用
- 电池供电设备（传感器节点、遥控器、便携式医疗设备）。
- 工业控制与嵌入式系统的上电复位与欠压监测。
- 通信设备、家电以及消费电子产品的稳态电源监护。
- 任何对待机功耗敏感且需要可靠电压检测的场合。
四、使用建议与典型电路
- 直连供电：将 VCC 接至系统电源（3.0V~5.5V），将输出连接到 MCU 的复位或中断引脚以实现上电/欠压告警。
- 去耦电容：建议在 VCC 与 GND 之间放置 0.1μF 陶瓷电容，靠近器件引脚以抑制干扰并保证检测稳定。
- PCB 布局：将电源走线短且宽，地线采用连续的接地平面，避免在器件敏感引脚附近布置大电流回路。
- 与 MCU 接口：若输出为开漏/开集电极结构，请外接合适的上拉电阻；若为推挽输出，可直接驱动低电平负载。
五、封装与可靠性
- 封装：SOT-23-3，三引脚设计，适合自动贴片工艺并节省板面空间。
- 温度与可靠性：在 -40℃ 至 +85℃ 的温度范围内能稳定工作，适应工业级与商用级应用。建议在高温环境下进行充分的系统测试以确认长期可靠性。
六、选型与注意事项
- 工作电压需求：确认系统电压始终落在 3.0V~5.5V 范围内，超出范围可能导致器件不能正确工作或损坏。
- 电流预算：静态电流 10μA 仅指器件本身静态消耗，工作态或输出驱动时总系统电流应综合评估。
- 接口兼容：在与 MCU 或其他逻辑器件连接前，确认输出电平与所驱动器件的容限及上拉需求。
- 环境应力：若用于震动、潮湿或极端温度环境，应参考厂商完整可靠性规范并考虑加固防护设计。
七、总结
ETA5001S2D 以其宽电压范围、极低静态电流和工业级温度性能，提供了一种简单而可靠的电源监测解决方案。对电池供电与低功耗系统尤为适用。结合良好的 PCB 布局与必要的去耦措施，可在多种应用中提高供电可靠性并延长系统寿命。若需更详细的电气特性表、输出类型或典型波形，请参考钰泰官方数据手册或联系供应商获取完整规格书。

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.
