MP8007HGV-Z 产品概述

MP8007HGV-Z 是 MPS 推出的一款高集成度以太网供电控制器(PSE),针对 IEEE 802.3af (PoE) 供电设备应用而设计。该器件支持 0V~57V 宽输入电压范围,单通道输出,最大向 PD 提供 13W 可用功率,封装为 QFN-28 (4×5 mm)。MP8007HGV-Z 集成多项保护与控制功能,适合交换机、PoE 注入器、机顶盒和各类网络终端供电方案。

一、主要特性

  • 支持标准:IEEE 802.3af(PoE)兼容,满足典型 13W PSE 需求。
  • 单通道设计:1 个功率通道,适用于对等或单端口 PSE。
  • 宽输入电压:0V ~ 57V 检测与控制能力,兼容各种以太网供电场景。
  • 最大输出功率:13W(PSE 可用功率),符合 802.3af 功率等级。
  • 芯片工作电压:内部工作电压 5.4V(芯片供电参考)。
  • 开关晶体管耐压:可承受高达 180V 电压应力,提升系统可靠性。
  • 限流能力:内部限制电流 840mA(短路/过流保护基准)。
  • 全面保护:热保护、过流保护、欠压保护、过压保护等多重保护机制。
  • PD 检测与断开识别:支持 PD 检测(检测/握手)与负载断开识别。
  • 内置 LDO:降低外部供电环节复杂度,简化外围元件。
  • 双事件分级检测:支持分级分类检测以实现稳健的分类与供电决策。
  • PGOOD 输出:提供功率就绪/状态指示便于系统级监控。
  • 工作温度:-40℃ 至 +125℃(TJ),适应工业级环境。

三、工作原理与功能说明

MP8007HGV-Z 在 PSE 系统中承担检测(Detection)、分类(Classification)、供电(Power Sourcing)及保护等关键功能。器件先通过 PD 检测电路辨识负载特性,支持双事件分级检测以应对复杂 PD 行为。分类过程完成后,MP8007HGV-Z 通过内部或外接功率晶体管将电源传递到线对,并在启动与运行过程中实施限流与过流管理(840mA 限制),同时监控输入输出状态并通过 PGOOD 引脚报告供电就绪状态。器件内置 LDO 为控制电路及外围逻辑提供稳定的驱动电压,简化系统设计。

全面的保护机制包括热关断、欠压锁定、过压保护及断开识别,配合高耐压晶体管,可在异常事件下保护系统与负载,提升整体可靠性。

四、封装与热设计建议

MP8007HGV-Z 采用 QFN-28 (4×5 mm) 封装,配有露出焊盘(thermal pad)以增强导热与散热能力。建议在 PCB 设计时:

  • 在封装下方设计多焊盘并与内部散热层(多层 PCB 的内部铜层)热连接;
  • 在外围布局尽量靠近大面积铜箔,避免热源聚集;
  • 对大电流路径使用宽铜线和多焊盘布线,降低寄生电阻与发热;
  • 保持关键模拟和数字信号线远离高开关噪声区域,确保检测与分类精度。

五、典型应用

  • PoE 交换机端口供电(单端口/多端口扩展设计中的单通道参考)
  • PoE 注入器与中间供电器(midspan)
  • IP 电话、接入点(AP)和无线网桥供电
  • 网络摄像机、门禁与工业以太网设备的远端供电系统

六、设计注意事项与推荐实践

  • PD 检测与分类精度依赖外围阻容及布局,请严格按参考设计匹配检测电阻网络;
  • 选择合适耐压与导通损耗的外置功率 MOSFET(若采用外置功率器件)以配合 180V 级别的耐压要求;
  • 在高温条件或连续大功率输出场景下,评估热管理(散热器、铜厚、空气对流)以避免过热触发热保护;
  • 利用 PGOOD 信号结合系统 MCU 实施上电序列与故障报警,提升系统可维护性;
  • 若系统需支持更高功率或多端口供电,可基于本器件拓展冗余与并联控制方案,但需注意功率与保护策略的协调。

七、总结

MP8007HGV-Z 是一款面向 IEEE 802.3af PoE 应用的高集成 PSE 控制器,凭借宽电压检测范围、13W 输出能力、丰富的保护功能及内部 LDO,能够显著简化 PoE 供电端设计,加速产品开发并提升系统可靠性。其 QFN-28 小尺寸封装和工业级工作温度使其在网络设备、安防设备与工业以太网供电中具有广泛的应用价值。

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.
