MP8001DS-LF-P

Overview

The MP8001DS-LF-P is a Powered Device (PD) controller compliant with the IEEE 802.3af standard for Power over Ethernet applications. It integrates a detection and classification circuit with a high-voltage switch rated for 100V. The device features a maximum on-resistance of 1.2 Ohms and a current limit of 420 mA. It operates within a supply voltage range up to 48 V, with a quiescent current of 240 uA. The component supports an output power capacity of 15 W and functions reliably across a temperature range from -40°C to +85°C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates a 100V withstand voltage DMOS switch for PoE power delivery
• Includes built-in thermal protection and surge current limiting capabilities
• Provides open-drain power good output indication
• Features temperature-compensated current limiting for overload protection

Applications

• IEEE 802.3af compliant Powered Devices
• Power over Ethernet LAN infrastructure components
• Network endpoint power management circuits

Procurement Notes

Verify the suffix 'P' indicates tape-and-reel packaging versus 'Z' for cut tape or other variants. Confirm RoHS compliance status through official documentation. Ensure the specific lot date code meets project requirements. Check for moisture sensitivity level handling instructions during storage. Validate that the SOIC-8 footprint matches the PCB design specifications.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af PD standards. The integrated switch eliminates external MOSFETs, reducing board space. Consider the 420 mA current limit when sizing downstream loads. The SOIC-8 package offers a compact solution for space-constrained network equipment. Verify thermal performance under maximum load conditions within the specified operating temperature range.

Part Context

This part belongs to the MP8001 series of PoE controllers manufactured by Monolithic Power Systems. It serves as a core power management element for network devices receiving power via Ethernet cables. The series provides standardized interfaces for PoE negotiation and power switching. It is designed to replace discrete solutions with a single integrated IC approach.

Replacement Considerations
