TLV803SDBZR-TP 产品概述

一、产品简介

TLV803SDBZR-TP(品牌:TECH PUBLIC / 台舟电子)是一款单通道电压监控器,采用SOT-23小型封装,监测电源电压并在低于设定阈值时产生复位信号。器件工作电压范围宽(1.0V 至 5.5V),阈值电压为2.93V,复位为低电平有效,输出为开漏结构,静态电流仅为2μA,适用于对功耗和面积敏感的便携与工业类应用。

二、主要特性

  • 监控通道:1路单电压监测
  • 工作电压:1.0V ~ 5.5V,兼容多种电源轨
  • 阈值电压:2.93V(用于判定复位/释放)
  • 复位有效电平:低电平有效(RESET 低表示系统处于复位)
  • 输出类型:开漏(需外接上拉电阻)
  • 静态电流(Iq):典型 2μA,适合电池供电系统
  • 工作温度:-40℃ ~ +105℃
  • 封装:SOT-23(适合表面贴装小体积设计)

三、典型应用

  • 电池供电的便携设备与可穿戴设备
  • MCU/FPGA/ASIC 的电源看门与上电监控
  • 工业控制与通信设备的电压完整性保护
  • 电源管理、电池管理系统与手持仪表

四、引脚与封装说明

TLV803SDBZR-TP 为 SOT-23 小封装,常见引脚功能包括 VCC(监控输入)、GND(地)、RESET(开漏输出)。由于RESET为开漏结构,需外部上拉电阻连接到所需的逻辑电平(通常为VCC或其它监控电源轨),以输出高电平释放复位。

五、使用建议与注意事项

  • 上拉电阻:根据负载与上电速度选择合适阻值(常用10kΩ~100kΩ),上拉到合适逻辑电平。
  • 去耦电容:在VCC引脚附近放置0.01µF~0.1µF陶瓷去耦,抑制瞬态噪声,保证阈值检测稳定。
  • 布局:元件靠近被监测电源引脚布置,短引线、良好地平面,以减少噪声干扰与引线压降。
  • 热与应力:器件额定工作温度为-40℃~+105℃,若应用环境温度接近极限,请注意热管理与长期可靠性。
  • 验证:在设计中应通过实验确认阈值、冒险上电情形与复位时序是否满足系统需求,必要时加上上电延时电路或外部复位延时。

六、可靠性与选型建议

TLV803SDBZR-TP 以低功耗、宽工作电压和小封装为主要优势,适合对电源完整性有严格要求的低功耗系统。选型时请结合目标系统的上电顺序、复位时序需求及环境温度,阅读完整器件规格书以确认阈值公差、复位保持时间与瞬态行为,确保在目标应用中取得稳定可靠的监控效果。若需更严格的温度或更复杂的多路监控功能,可考虑相应扩展型号或配套电路。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
