MP6540GU-Z 产品概述
一、产品简介
MP6540GU-Z 是 MPS 推出的一款集成型三相电机驱动器，封装为 26 引脚 QFN（5×5 mm）。器件内部集成高侧/低侧功率 MOSFET，支持三半桥输出，适用于对体积、效率和系统集成度有较高要求的无刷直流（BLDC）电机控制场景。器件支持软开关功能，可在降低开关损耗与电磁干扰的同时提升系统可靠性。
二、主要规格
- 驱动类型：三相（3 半桥）
- 集成 FET：是（高/低侧 MOSFET 集成）
- 连续输出电流：3 A
- 峰值电流：10 A
- 工作电压范围：5.5 V ～ 35 V
- 导通电阻（RDS(on)）：约 50 mΩ（单管典型值）
- 静态电流（Iq）：约 800 μA
- 工作温度范围：-40 ℃ ～ +125 ℃
- 封装：QFN-26（5×5 mm）
三、关键特性与优势
- 集成 FET 设计：减少外部器件，简化 PCB 布局与 BOM，缩短开发周期。
- 软开关支持：在开关瞬态控制上优化，降低开关损耗与 EMI，适合对噪声敏感的应用。
- 宽电压范围与高峰值电流能力：适配多种电源与启动工况，兼顾能量密集型瞬态需求。
- 低静态电流：在待机或低速情况下有利于整机能耗控制。
- 紧凑封装：QFN-26(5×5) 小型化设计，便于空间受限的应用。
四、典型应用
- 无人机与航模动力系统（小型 BLDC 电机）
- 云台、相机防抖与精密伺服驱动
- 工业自动化中小功率驱动器、风机和水泵控制
- 办公设备与家电中的高效电机控制模块
五、设计与使用建议
- 电源去耦：在 VCC/PVCC 等电源引脚附近放置低 ESR 陶瓷电容，减小开关瞬态电压尖峰。
- 热管理：尽量在 PCB 下方采用散热过孔和铜箔扩散热量，保证长期连续 3A 工作时温升可控。
- 布局注意：功率回路走线短而粗，地线分割（模拟地/功率地）以降低噪声耦合。
- 保护与测量：建议在系统层面加入过流、欠压与过温保护策略，并设计合理的电流检测与滤波方案以配合软开关控制。
六、总结
MP6540GU-Z 提供了高集成度、低导通损耗与软开关技术相结合的三相驱动方案，适合体积受限且对效率、EMI 有要求的中小功率电机应用。通过合理的 PCB 布局与热设计，可在 5.5–35V 电源范围内稳定驱动负载，满足多样化的工程需求。
Request for quote
Send RFQ
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.
