TLV803EA30DBZR 产品概述
一、产品简介
TLV803EA30DBZR 是德州仪器（TI）出品的一款超低功耗电压监控器（复位IC），用于在电源电压低于设定阈值时产生复位信号，确保微控制器和数字系统在电源异常或上电阶段不会进入不确定状态。该器件为单路监控、低电压工作、开漏主动低电平输出的简单可靠解决方案，特别适合电池供电与低功耗终端设备。
二、主要特性
- 输出类型：开漏（Open-drain），复位为低电平有效，便于与多种系统复位线共用或实现线与或逻辑。
- 监测阈值：3.08 V（型号标识为“30”，适用于3.0V类系统）。
- 工作电压范围：1.7 V 至 6.0 V，适配多种供电轨。
- 静态电流（Iq）：典型值 250 nA，极低待机功耗，利于延长电池寿命。
- 复位超时：约 200 ms，保证上电或电压恢复时系统有足够时间完成初始化。
- 工作温度范围：-40 ℃ 至 +125 ℃，满足工业级环境要求。
- 看门狗：无（仅为电压监控/复位功能）。
- 封装：SOT-23-3，体积小，便于空间受限电路板布局。
三、关键参数
- 受监控电压数：1 路。
- 输出形式：开漏需外接上拉电阻，上拉电压应不超过器件工作电压范围。
- 热稳定性与可靠性符合TI规范，适合长期运行的工业与商用设备。
四、典型应用场景
- MCU、ASIC 等数字系统的电源复位保护。
- 电池供电设备（可穿戴、传感器节点、遥测终端等）对低静态电流的要求。
- 通讯设备、工业控制、仪表等需要可靠上电复位与电压监测的场合。
- 多复位源共享线（open-drain 方式）或系统复位链路设计。
五、封装与引脚说明
- 封装形式为 SOT-23-3，三个引脚分别为 VDD、GND、RESET（开漏）。
- 典型接法：VDD 接电源，GND 接地，RESET 为开漏输出需外接上拉电阻至 VDD 或系统复位电平。
六、使用建议与注意事项
- 由于输出为开漏，请在外部加适当上拉电阻（典型值 10 kΩ~100 kΩ 取决于响应速度和功耗权衡）。
- 上电和电源瞬态时，外部去耦电容（如 0.1 μF）可以降低误触发风险并改善阈值稳定性。
- RESET 输出不能被拉至高于 VDD；如需与不同电平域接口，请采用开集输出兼容的中间电平或缓冲电路。
- 在高噪声或长引线环境下，注意布局走线和地线回流以避免误复位。
- 若系统需要看门狗功能，应另配专用看门狗电路或选择带看门狗的监控器件。
七、替代与选型提示
- 若需要不同阈值（如 2.5 V、4.5 V 等）或带看门狗/推挽输出等额外功能，可在 TI 的电压监控器系列中选择对应型号。
- 在空间或功耗极端受限场景，比较静态电流与封装后再行选型，确保满足系统待机与启动需求。
TLV803EA30DBZR 以其超低静态电流、宽工作电压和工业级温度范围，为对上电复位稳定性和低功耗有较高要求的产品提供了经济且易用的解决方案。

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.
