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。
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。
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:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
