MP6612DGF-Z 产品概述

一、主要特性

MP6612DGF-Z 是一款由 MPS 推出的集成型 H 桥直流电机驱动器,内置功率 MOSFET,适用于单电源供电的低压大电流电机驱动场合。器件关键参数如下:

  • 工作电压:4V ~ 40V
  • 输出电流:5A(器件级别能力,实际连续输出受散热限制)
  • 静态电流:Iq ≈ 1 µA(非常适合电池供电的低静态损耗系统)
  • 工作温度:-40℃ ~ +125℃
  • 封装:TSSOP-20-EP(带底部散热焊盘)
  • 主要功能:主动制动(Active Braking)、电流采样/调节(Current Sense/Adjust)、DIR/ENBL 方向与使能控制

二、功能描述

MP6612DGF-Z 内置完整 H 桥结构,集成高侧与低侧 FET,简化外围功率组件。器件提供电流采样输出/通道,可通过外接采样电阻实现电流限制与闭环监控;内置主动制动功能,通过短接电机绕组实现快速制动,便于运动控制中的快速停止与定位。器件采用 DIR(方向)与 ENBL(使能/可用于 PWM)逻辑接口,能方便地与 MCU 或运动控制器配合实现正反转与转速调节。

三、保护与可靠性

为提高系统可靠性,MP6612DGF-Z 在设计上考虑了多种保护机制(如过流、过温、欠压保护等常用保护措施),以防止异常工况对器件和负载造成损伤。具体保护门限和行为请参见官方数据手册以获得准确数值与触发逻辑。

四、典型应用

  • 电机驱动与运动控制(直流电机、步进驱动的简单驱动场景)
  • 执行器与阀门控制
  • 点火/燃油泵等汽车电子(需满足汽车级验证)
  • 便携式/电池供电设备中需要低静态电流的驱动单元

五、封装与热管理建议

TSSOP-20-EP 封装带有底部散热焊盘,推荐在 PCB 设计中扩大焊盘面积并采用多层过孔,形成良好的热流通路,以支持接近 5A 的输出需求。实际连续输出电流受 PCB 散热、环境温度与占空比影响较大;设计时请根据功耗估算并留足热裕量。

六、设计与使用注意事项

  • 电流检测:建议将电流采样电阻布置靠近器件 CS 引脚并使用低噪布局,以获得稳定的电流反馈。
  • 控制接口:DIR/ENBL 可直接与 MCU 驱动;若使用 PWM 调速,通常通过 ENBL 输入实现占空比控制。
  • 布局:功率回路走线宽短,旁路电容靠近供电引脚放置,减少寄生电感和噪声。
  • 参考资料:在产品选型与系统集成前,请下载并阅读 MPS 官方数据手册,确认参数、引脚定义与典型应用电路。

MP6612DGF-Z 以其宽电压范围、低静态电流与集成功率 FET 的集成度,适合对体积、功耗和成本有要求且需可靠控制单轴直流电机或小功率执行器的应用场景。

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
