TB67H451FNG(O,EL) 产品概述
一、产品简介
TB67H451FNG 是东芝（TOSHIBA）推出的一款集成MOSFET的单通道H桥驱动器，封装为SOIC-8，适用于直流电机、电磁阀、继电器等负载的单桥驱动控制。器件工作电压范围宽（4.5V～44V），额定输出电流可达3A，静态待机电流仅1μA，适合对功耗敏感的便携或长待机系统。
二、主要性能参数
- 集成FET：是（内部包含高/低侧功率MOSFET）
- H桥数量：1
- 输出电流：3A（实际连续电流受散热限制）
- 工作电压：4.5V～44V
- 导通电阻（RDS(on)）：约600mΩ（典型值或单次管道）
- 静态电流（Iq）：1μA（待机极低）
- 工作温度：-40℃～+85℃
- 封装：SOIC-8 注：标注值以厂商数据手册为准，设计时应参考典型、极限条件与热阻参数。
三、应用场景
- 小型直流减速电机驱动（玩具、家电、便携设备）
- 电磁阀、微型执行器与单向线圈负载
- 低功耗系统中的单路驱动与开关控制
- 需要宽电源范围与低待机电流的场合
四、设计注意事项
- 散热与功耗：在最大电流下功耗较大（P ≈ I^2·RDS(on)，例如3A时理论损耗约5.4W），实用设计中需考虑PCB散热、铜箔面积与热沉，建议在典型工况下进行热仿真并留裕量。
- 反向电压与浪涌保护：负载反电动势较大时应并联TVS或RC缓冲网络，必要时加外部快恢复二极管或吸收器避免电压尖峰超限。
- 旁路与退耦：VCC近端放置低ESR电容（如10μF并并联0.1μF）以抑制开关瞬态。
- 引脚与布局：SOIC-8封装引脚通常包含VCC、GND、IN/EN、OUT等，实际信号命名与功能请以数据手册为准；布局应缩短功率回路、加布热铜并使用过孔下导热。
- 保护与控制：建议在系统层面加限流、软启动或PWM调制策略以减小启动冲击和热应力；若需故障检测或过热保护，配合外部监测电路使用。
五、总结
TB67H451FNG 在保持低待机电流的同时提供宽电压范围和单通道H桥驱动能力，适用于多种中小功率执行器控制场景。设计时应重点关注散热与瞬态保护，严格参照东芝数据手册的引脚定义和电气特性，以保证可靠性与长期稳定运行。若需进一步电气时序、引脚表及典型应用电路，请查阅厂商完整资料。

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.
