MP8008GV-Z

Overview

The MP8008GV-Z is a fully integrated IEEE 802.3af/at-compatible Power over Ethernet (PoE) Powered Device (PD) interface with an internal flyback controller. It operates within a supply voltage range of 12 V to 57 V and supports a maximum output power of 25 W. The device features a 480 mOhms maximum on-resistance switch and limits operating current to 840 mA. It utilizes a QFN-28 package and functions reliably across temperatures from -40 C to +125 C.

Feature Summary

Integrates PD interface with detection, classification, and surge current limiting alongside a peak current mode flyback PWM controller.
Includes a 100V thermal hot-swap MOSFET and a dedicated gate driver for external high-current MOSFETs.
Supports auxiliary adapter ring powering with indicators for power good and Type-2 PSE status.
Features frequency hopping in light load conditions to enhance efficiency.

Applications

High-performance PoE powered devices requiring front-end integration
Network infrastructure equipment compliant with IEEE 802.3af/at standards
Applications utilizing auxiliary adapter ring powering

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when ordering. Confirm the QFN-28 package dimensions match the design footprint. Ensure the input voltage range aligns with the PoE source capabilities. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Selection Notes

Select this component for designs needing a compact solution that combines PD interface logic with power conversion. It suits applications requiring support for both 802.3af and 802.3at standards. Consider the external MOSFET requirement for the flyback stage when evaluating system efficiency and thermal management needs.

Part Context

This part belongs to the MP8008 series from Monolithic Power Systems. It is designed specifically for PoE applications, integrating control and power stages to reduce external component count. The series targets networked devices requiring reliable power delivery over Ethernet cables.
