MP8007HGV-Z

Overview

The MP8007HGV-Z is a fully integrated IEEE 802.3af-compatible Powered Device (PD) interface with an internal DC-DC converter, designed for 13W Power over Ethernet applications. It operates within a supply voltage range of 0V to 57V and supports both isolated flyback and non-isolated buck topologies. The device features a 480 mΩ maximum on-resistance hot-swap MOSFET, an 840 mA steady-state current limit, and a 120 mA startup current limit. It utilizes a QFN-28 (4mm x 5mm) package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Fully integrated PD interface compliant with IEEE 802.3af/at standards
• Supports primary-side regulated flyback topology without optocouplers
• Includes integrated 180V power MOSFET for wide input voltage ranges
• Provides comprehensive protection against overcurrent, overvoltage, and overheating

Applications

• Isolated 13W PoE powered devices
• Non-isolated PoE powered devices
• Ethernet-powered industrial equipment
• Network infrastructure endpoints

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer documentation. Confirm the QFN-28 package dimensions match design constraints. Ensure compatibility with 802.3af/at classification protocols during integration. Cross-reference ordering part numbers with official MPS catalogs to avoid variant mismatches.

Selection Notes

Select this component for designs requiring a compact solution for 13W PoE applications. It is suitable for both isolated and non-isolated architectures due to its flexible converter modes. The integrated MOSFET reduces external component count. Verify thermal performance requirements align with the specified operating temperature range.

Part Context

The MP8007 series represents Monolithic Power Systems' integrated approach to PoE powered devices. This model combines the PD controller and power conversion stage into a single chip. It targets applications needing high efficiency and minimal footprint in networked electronic systems.
