MP5991GLU-Z 是一款面向热插拔(Hot‑Swap)应用的智能电源保护器件,由 MPS(Monolithic Power Systems)推出。器件内置功率 FET,单通道设计,工作电压范围 4V 至 16V,能够在高达 50A 的连续电流下工作,典型导通电阻 RDS(on) 为 1 mΩ。封装为 LGA-32 (5×5 mm) 表面贴装,器件尺寸 5 mm × 5 mm,工作温度范围 −40℃ 至 +125℃。内建软启动、欠压锁定、过流保护、短路保护和热保护,适合服务器、通信、电源模块以及工业电源分配等场景的输出级、负载上电与电源冗余管理。
MP5991GLU-Z 在上电时通过软启动电路控制内部 FET 以受控速率导通,从而限制浪涌电流并避免对后端负载或电容造成冲击。欠压锁定功能保证在输入电压不足时不导通,避免系统异常。过流保护与短路保护通过检测通道电流并在超过设定阈值时限流或快速断开,结合热保护可在器件过热时安全关断并在温度恢复后按策略重试,确保系统在异常工况下的可恢复性与可靠性。
为发挥器件的导热与低损耗优势,建议在 PCB 布局时:
结语:MP5991GLU-Z 将低导通损耗与全面保护功能集成在小尺寸封装中,适合要求高电流、快速保护与可靠热插拔能力的应用场合。合理的 PCB 布局与热管理能够充分发挥其性能,显著提升系统的可靠性与可维护性。若需详细引脚定义、电气特性曲线与参考设计,请参阅 MPS 官方数据手册与参考电路。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
