MP8004GQW-Z

Overview

The MP8004GQW-Z is a Power over Ethernet (PoE) Powered Device interface and DC/DC flyback converter compliant with IEEE 802.3af standards. It integrates a 100V PD switch and a 150V DC/DC power switch within a single QFN-20 package. The device supports up to 13W output power, features internal soft-start, auto-retry, and programmable frequency operation. It includes comprehensive protection mechanisms such as overcurrent, short-circuit, and overvoltage protection.

Feature Summary

• Integrates a 100V PD switch with surge current limiting for slow input capacitor charging
• Includes a 150V DC/DC power switch capable of efficient 13W power conversion
• Features automatic retry functionality and internal soft-start capabilities
• Provides complete protection against overcurrent, short-circuit, and overvoltage conditions

Applications

• IEEE 802.3af PoE powered devices
• LAN interface circuits
• Power over Ethernet controllers
• Flyback DC/DC converters in network equipment

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when ordering. Confirm the QFN-20 package dimensions match your PCB footprint requirements. Ensure the supply voltage range aligns with your system's PoE input specifications. Check for any alternative packaging options if reel quantities are required for production.

Selection Notes

Select this component for applications requiring integrated PoE detection and classification alongside high-voltage DC/DC conversion. It is suitable for designs needing built-in surge protection and thermal management features. Consider the QFN-20 package size for space-constrained layouts. Verify compatibility with IEEE 802.3af standards for proper network integration.

Part Context

The MP8004 belongs to Monolithic Power Systems' portfolio of PoE interface solutions. It combines PD interface functions with a flyback converter to simplify design complexity. This integration reduces the component count compared to discrete solutions. The device targets industrial and commercial networking applications requiring reliable power delivery.
