MP8007GV-P

Overview

The MP8007GV-P is a fully integrated Powered Device (PD) interface compliant with IEEE 802.3af/at standards, designed for 13W Power over Ethernet applications. It features an operating voltage range of 0V to 57V and supports both isolated primary-side regulated flyback and non-isolated buck converter topologies. Key electrical parameters include a maximum on-resistance of 480 mOhms, a startup current limit of 120mA, and a steady-state current limit of 840mA. The device incorporates an internal 180V power MOSFET and operates within a temperature range of -40°C to +125°C. It is housed in a QFN-28 (4mm x 5mm) package.

Feature Summary

• Fully integrated PD interface supporting detection, classification, and protection functions per IEEE 802.3af/at specifications.
• Supports primary-side regulated flyback topology without optocouplers or non-isolated buck conversion modes.
• Includes an integrated 180V power MOSFET for wide input voltage compatibility.
• Provides comprehensive protection against overcurrent, overvoltage, open-loop feedback, and overheating.

Applications

• Isolated 13W PoE powered devices
• Non-isolated PoE powered devices
• PoE front-end power supply designs

Procurement Notes

Verify the specific suffix 'GV-P' against official Monolithic Power Systems documentation to confirm pinout and thermal characteristics. Ensure compliance with RoHS directives as indicated in manufacturer records. Confirm moisture sensitivity levels and recommended soldering profiles prior to assembly. Cross-reference the datasheet version to validate feature availability and operational limits.

Selection Notes

Select this component for designs requiring a compact solution for 13W PoE applications. The integrated flyback controller eliminates the need for external optocouplers, reducing bill of materials. Choose the buck mode for non-isolated applications to minimize footprint. Ensure the design accommodates the QFN-28 package thermal requirements and supports the specified input voltage range.

Part Context

The MP8007 belongs to the MP8007 series of integrated PoE PD interfaces from Monolithic Power Systems. It consolidates the PD controller and power conversion stages into a single chip. This integration simplifies the design process for Ethernet-powered equipment by handling protocol compliance and power regulation internally.

Replacement Considerations

MP8007GV-Z is listed as a variant within the same product line. Verify if the suffix change affects packaging or specific electrical tolerances before substitution.
