TPS3422EGDRYR 产品概述
一、产品简介
TPS3422EGDRYR 是德州仪器（TI）推出的一款低功耗电源监控/复位器，适用于对单路电压进行监督并生成系统复位信号的场合。器件采用小型 USON-6（1.0 mm × 1.5 mm）封装，工作电压范围宽（1.6 V 至 6.5 V），在嵌入式系统、电池供电设备与工业电子中能提供可靠的上电复位和电压异常保护。
二、主要特性
- 输出类型：开漏（open-drain），便于实现线-或（wired-OR）或与外部拉拔电阻配合使用。
- 复位有效电平：低电平有效（active-low reset），符合多数 MCU/逻辑复位接口要求。
- 受监控电压通道数：1 路，专注单点电源监控。
- 复位超时：典型复位延时 400 ms，保证电源稳定后系统有足够时间完成上电初始化。
- 看门狗定时器：无，功能定位为电压监控与复位生成，不带独立看门狗。
- 静态电流（Iq）：仅 250 nA（超低静态电流），适合待机、低功耗场景。
- 工作温度范围：-40 ℃ 至 +125 ℃，满足工业级温度要求。
三、典型应用
- MCU/MPU 上电复位与电源监控
- 电池供电或便携式设备的低功耗电源管理
- 工业控制模块与通信终端的可靠复位保护
- 电源管理子系统中作为单通道电压监测器
四、设计与使用要点
- 由于输出为开漏结构，系统需外接合适的上拉电阻，上拉电压应与器件工作电压范围匹配且不超过系统允许电压。
- 400 ms 的复位超时使系统在电源稳定后有充分时间完成初始化；在对复位时序有更严格要求的应用中，请结合外部电路或系统软件进行配合。
- 极低的静态电流（250 nA）适合长期在线且对功耗敏感的应用，但在噪声环境下应注意电源滤波与旁路，保证监测精度与稳定性。
- 封装为 USON-6（1×1.5 mm）超小型封装，焊接和热管理时注意焊盘设计与回流工艺，确保可靠的焊接强度和热散逸。
五、封装与订购信息
- 品牌：TI（德州仪器）
- 型号：TPS3422EGDRYR
- 封装：USON-6（1×1.5 mm）
如需批量采购或了解更详细的电气特性、引脚排列与典型应用电路，请参阅 TI 官方数据手册与参考设计，以获得完整的规格与推荐实装方案。
六、总结
TPS3422EGDRYR 以其超低静态电流、宽供电范围、工业级温度能力和简单可靠的开漏复位输出，适合用于各种需要单点电压监控与稳健复位功能的系统。合理的 PCB 布局与外部上拉设计可充分发挥器件在低功耗与可靠性方面的优势。

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.
