MP8007HGV-P

Overview

The MP8007HGV-P is a fully integrated Powered Device (PD) interface compliant with IEEE 802.3af standards, designed for Power over Ethernet applications. It supports up to 13W output power via an integrated flyback or buck converter. The device features a maximum operating voltage of 57V and a current limit of 840mA. Its maximum on-resistance is 800 mOhms, with a quiescent current of 450 uA. It operates within a temperature range of -40°C to +125°C and is housed in a QFN-28 package.

Feature Summary

• Fully integrated 802.3af-compatible PD interface supporting both flyback and buck converter topologies
• Integrated 180V power MOSFET enabling wide input voltage application support
• Primary-side regulation capability for flyback mode eliminating the need for optocouplers
• Comprehensive protection mechanisms including over-current, over-voltage, open-loop, and over-temperature

Applications

• Isolated 13W Power over Ethernet powered devices
• Non-isolated 13W Power over Ethernet powered devices
• PoE endpoints requiring primary-side regulated power conversion

Procurement Notes

Verify the specific suffix 'P' indicates cut-tape packaging availability against reel-only variants like 'Z'. Confirm lead times as they may vary significantly between distributors. Ensure compatibility with moisture sensitivity levels if storage conditions are critical. Cross-reference the datasheet version to confirm pinout consistency with existing designs.

Selection Notes

Select this component when designing systems requiring full IEEE 802.3af compliance with integrated power conversion. Choose the HGV variant for lower on-resistance compared to standard versions if efficiency is prioritized. Consider the QFN-28 footprint for space-constrained layouts. Verify thermal management requirements given the high current capabilities and operating temperature range.

Part Context

This part belongs to the MP8007 family of PoE PD interfaces from Monolithic Power Systems. It integrates detection, classification, and power switching functions alongside a DC-DC converter. The family supports both isolated and non-isolated architectures, simplifying design by reducing external component count while maintaining robust protection features.

Replacement Considerations

MP8007HGV-Z serves as a reel-packaged alternative with identical electrical characteristics. MP8007GV-P offers similar functionality but with different on-resistance specifications. Verify package dimensions and pin assignments before substitution to ensure mechanical compatibility.
