MP3924GU-Z 产品概述
一、产品简介
MP3924GU-Z 是 MPS 推出的以太网供电（PoE）控制器，作为供电设备（PSE）级别的核心控制器，完全兼容 IEEE 802.3af 和 IEEE 802.3at（PoE+）标准。器件工作电压为 3.3V（芯片内核电源），外部供电输入 VPWR 支持 44V～57V，适配典型 PoE 系统的输入范围。器件支持 4 路通道设计，适合多端口交换机、注入器与中间供电设备。
二、主要特性
- 支持 IEEE 802.3af（PoE）与 IEEE 802.3at（PoE+）协议；
- 4 路通道，便于多端口 PSE 架构集成；
- 芯片工作电压 3.3V，VPWR 输入范围 44V～57V；
- 完善保护功能：过载保护、过流保护、故障保护；
- 宽温工作能力：-40℃ 至 +125℃（结温 TJ 级）；
- 封装：QFN-32（5x5），便于高密度板级布局与散热设计；
- 品牌：MPS（Monolithic Power Systems）。
三、功能描述
MP3924GU-Z 主要负责 PoE 系统中的检测、分类、上电切换与保护管理。设备在 PD 检测与分类阶段提供精准的识别与握手支持，随后按 IEEE 规范控制供电通路，实现按端口分配功率。内置的保护逻辑可在短路、过流或异常故障时快速响应，限制输出电流并隔离故障端口，保障系统与负载安全。器件的 3.3V 内核电源与宽 VPWR 范围使其能在常见 PoE 拓扑与电源总线上稳定工作。
四、典型应用
- PoE 交换机与路由器的 PSE 管理单元；
- PoE 注入器和中间供电（midspan）设备；
- 企业及工业级 AP（无线接入点）供电模块；
- 安防监控系统中的多通道供电方案；
- VoIP 电话与其他以太网供电的终端集中供电装置。
五、封装与热/电特性
MP3924GU-Z 采用 QFN-32（5x5mm）紧凑封装，有利于高密度布板与可靠接地/散热设计。器件在结温范围 -40℃ 至 +125℃ 下额定工作，适合工业级与苛刻环境的长期运行。VPWR 的 44V～57V 输入范围兼容 PoE 标准供电电压，并为系统设计提供一定裕量以应对线路压降与电源波动。
六、设计要点与系统优势
在系统集成时，建议关注输入滤波与去耦、散热路径以及每路通道的电流监控策略。利用器件内置的保护功能可简化外部保护电路，但对关键路径仍应做合理的 PCB 铜厚与热管理。MP3924GU-Z 提供标准兼容性与多通道集成度，适用于需在有限 PCB 面积内实现可靠 PoE PSE 功能的产品，能显著缩短设计周期并提升系统可靠性。

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.
