MP8007GV-Z

Overview

The MP8007GV-Z is a fully integrated IEEE 802.3af/at-compatible Powered Device (PD) interface from Monolithic Power Systems, designed for isolated or non-isolated 13W Power over Ethernet applications. It features an internal DC-DC converter supporting primary-side regulated flyback or buck topologies. Key electrical parameters include a 100V hot-swap MOSFET with a maximum on-resistance of 480 mΩ, a 120mA startup current limit, and an 840mA steady-state operating current limit. The device operates within a supply voltage range of 0V to 57V and supports a programmable switch peak current limit up to 3A. It utilizes an integrated 180V power MOSFET and is housed in a QFN-28 (4mm x 5mm) package.

Feature Summary

• Fully integrated PD interface compliant with IEEE 802.3af/at standards, including detection, classification, and protection mechanisms.
• Supports both primary-side regulated flyback topology without optocouplers and low-side switch buck converters for compact designs.
• Integrates a 100V hot-swap MOSFET and an 180V power MOSFET to minimize external component count.
• Includes comprehensive protection features such as over-current, over-voltage, open-loop, and over-temperature protection.

Applications

• Isolated 13W Power over Ethernet powered devices
• Non-isolated PoE applications requiring minimal footprint
• Primary-side regulated flyback power supplies
• Low-side switch buck converter implementations

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with your target IEEE 802.3af/at implementation requirements. Cross-reference the QFN-28 thermal pad design guidelines during layout. Confirm that the selected variant meets all environmental compliance standards required for your final assembly process.

Selection Notes

Select this component for applications requiring a highly integrated solution for 13W PoE systems. It is suitable for designs prioritizing reduced bill-of-materials through primary-side regulation or compact non-isolated buck architectures. Consider the 180V internal MOSFET rating for wide input voltage ranges. Evaluate the QFN-28 package constraints for thermal management and PCB space availability compared to discrete solutions.

Part Context

The MP8007 series represents Monolithic Power Systems' approach to simplifying PoE PD designs by combining interface logic and power conversion in a single chip. This integration addresses the complexity of traditional multi-component PoE front-ends. The GV-Z suffix denotes a specific commercial grade variant within the MP8007 family, optimized for standard industrial temperature ranges and surface-mount assembly processes.

Replacement Considerations

MP8007GV-P is listed as a direct substitute within the same product family.
