MP8020GQV-Z

Overview

The MP8020GQV-Z is a Power over Ethernet (PoE) Powered Device interface IC from Monolithic Power Systems, compliant with IEEE 802.3af, 802.3at, and 802.3bt standards. It operates within a supply voltage range of 0 V to 57 V and supports a current limit of 900 mA. Designed for robust performance in harsh environments, the component functions reliably between -40°C and +125°C. It utilizes an SMD/SMT installation style in a QFN-18 package.

Feature Summary

• Supports multiple PoE standards including 802.3af, at, and bt
• Integrated powered device interface for LAN applications

Applications

• IEEE 802.3af/at/bt PoE powered devices
• LAN interface circuits

Procurement Notes

Verify the specific suffix Z indicates lead-free compliance against the manufacturer's official documentation. Confirm the QFN-18 package dimensions and pinout match your PCB layout requirements. Ensure the 900 mA current limit and 57 V maximum operating voltage align with your system design constraints before finalizing procurement.

Selection Notes

Select this component when designing systems requiring support for the latest 802.3bt PoE standards alongside legacy af and at protocols. The wide operating temperature range makes it suitable for industrial or outdoor deployments. Verify that the QFN-18 footprint fits within your board space limitations compared to other MPS PoE controllers.

Part Context

This part belongs to the MPS Power Switch ICs category specialized for PoE and LAN applications. It serves as a critical interface component for powered devices, managing power delivery according to IEEE standards. It differs from standard switching regulators by focusing on PoE protocol compliance and interface management rather than general DC-DC conversion.

Replacement Considerations

Consult official MPS substitution guides for verified alternatives. Generic cross-references are not recommended due to specific interface timing and protocol requirements inherent to PoE PD controllers.
