MP8017GL-P

Overview

The MP8017GL-P is a Power over Ethernet Powered Device (PoE-PD) solution from Monolithic Power Systems, compliant with IEEE 802.3af standards. It integrates an active clamp flyback converter capable of primary or secondary side regulation. The device operates within a wide input voltage range of 0 V to 57 V and supports a current limit of 1.5 A. Designed for surface-mount installation in a QFN-19 package, it functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates an active clamp flyback converter supporting both primary and secondary side regulated architectures
• Fully compatible with IEEE 802.3af PoE-PD standards for network-powered applications
• Features integrated current limiting to protect the powered device under fault conditions

Applications

• IEEE 802.3af compliant Powered Devices
• Power over Ethernet LAN infrastructure endpoints
• Network-connected industrial control modules

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and regulatory compliance status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm the technical specifications align with your design requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring strict adherence to IEEE 802.3af power delivery protocols. The integrated active clamp topology simplifies design by reducing component count compared to discrete solutions. Consider the QFN-19 package dimensions and thermal dissipation capabilities relative to your enclosure constraints and ambient operating temperatures.

Part Context

This part belongs to the Monolithic Power Systems portfolio of power management integrated circuits. It serves as a specialized interface between Ethernet data lines and local power rails, enabling devices to draw power directly from the network cable while maintaining signal integrity.

Replacement Considerations

Consult official MPS substitution guides for verified alternatives. Generic replacements may lack the specific IEEE 802.3af compliance or integrated flyback controller architecture.
