TB67H450FNG(O,EL) 产品概述
一、概述
TB67H450FNG(O,EL) 为东芝（TOSHIBA）推出的单通道 H 桥驱动器，封装为 SOP-8，内部集成功率 FET，适用于中小功率直流电机和线性致动器驱动场景。工作电压范围宽（4.5V 至 44V），能够在较大输入电压范围内稳定工作，最高输出持续电流等级为 3A，适配多种嵌入式和工业应用。
二、主要电气参数
- 集成FET：是（内部集成功率场效应管，简化外部功率器件设计）
- H 桥数量：1（单通道双向驱动）
- 输出电流：3A（额定输出能力）
- 工作电压：4.5V ~ 44V（宽电压输入，适应多种供电方案）
- 导通电阻（RDS(on)）：600 mΩ（影响功耗与发热）
- 静态电流（Iq）：1 μA（待机功耗低，有利于电池供电系统）
- 工作温度：-40 ℃ ~ +85 ℃（工业级温度范围）
- 封装：SOP-8（贴片封装，便于 PCB 布局与自动化组装）
三、典型应用场景
适合驱动小型直流电机、步进电机低速档位、微型泵、风扇、打印机构件、家电面板中的执行器以及便携式和工业控制设备中要求双向驱动的场合。由于静态电流低，也适用于以电池供电、待机时间要求长的产品。
四、设计与使用建议
- 电源去耦：在器件电源引脚附近放置合适容值的高频陶瓷与钽电容，抑制瞬态电压尖峰。
- 保护措施：在有较强电感负载（如电机）时，应在输入端添加 TVS 或浪涌抑制，必要时在 PCB 布局中考虑增加滤波网络。
- 散热与布局：RDS(on) 为 600 mΩ，在高电流工作时会产生显著功耗，建议留出足够铜箔面积作为散热路径，避免连续满载运行超温。
- 驱动与控制：参考东芝官方数据手册中推荐的输入驱动时序与上升/下降斜率控制，确保 H 桥开关转换期间的稳定与安全。
五、注意事项
- 本概述基于给定基础参数进行整理，具体保护特性（如欠压/过热/限流行为）与引脚定义、时序请以东芝官方数据手册为准。
- 在实际设计中，应进行热仿真和电磁兼容验证，确保在目标应用的工作循环和环境温度下满足可靠性要求。
若需，我可以帮助检索并解析官方数据手册要点，或者根据您的电源与负载条件给出 PCB 布局与散热设计建议。

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.
