LM5071MT-80/NOPB

Overview

The LM5071MT-80/NOPB is a Power over Ethernet (PoE) Powered Device controller compliant with IEEE 802.3af standards. It integrates an 80V, 1Ω, 400mA internal MOSFET and supports auxiliary power input from 12V AC adapters. The device operates on a supply voltage of 1.8V to 60V with a quiescent current of 1.5mA. It features a 1MHz interface, a 6.25V UVLO threshold, and auxiliary sensing capabilities. Packaged in a 16-pin TSSOP, it functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates an 80V, 1Ω, 400mA internal MOSFET for efficient power delivery
Supports auxiliary power input compatible with 12V AC adapters
Includes auxiliary sense functionality for enhanced power management

Applications

Industrial PoE powered devices requiring auxiliary power
Commercial networked equipment with high power demands
IEEE 802.3af compliant endpoint hardware

Procurement Notes

Verify the complete part number including the /NOPB suffix to ensure lead-free compliance and specific package variant accuracy. Confirm that the 16-TSSOP package matches the target PCB footprint. Ensure the design supports the 1.8V to 60V supply range and 1MHz interface requirements specified in the official datasheet.

Selection Notes

Select this component when an integrated solution for 802.3af PoE is required alongside auxiliary power capability. The internal 400mA MOSFET simplifies design compared to external switch implementations. Verify that the 60V maximum supply voltage aligns with the system's operational limits and that the 16-pin TSSOP package fits the mechanical constraints.

Part Context

This component belongs to the Texas Instruments LM5071 family of PoE controllers. It is designed specifically for Powered Devices (PD) that need to draw power from both the Ethernet cable and an auxiliary source. The device streamlines compliance with IEEE 802.3af standards while providing flexibility for higher power applications through its auxiliary interface.
