LM5072MHX-80/NOPB

Overview

The LM5072MHX-80/NOPB is a Power over Ethernet (PoE) controller compliant with the IEEE 802.3af standard, designed for use as a Powered Device (PD). It operates within a supply voltage range of 9V to 70V and supports a maximum power output of 12.95W. The device integrates both high-side and low-side switches, eliminating the need for external MOSFETs. It features a single channel configuration housed in a 16-HTSSOP package. The component functions reliably across an extended temperature range from -40°C to +125°C, with a maximum supply current of 2mA.

Feature Summary

• Integrates internal high-side and low-side switches for simplified circuit design
• Supports IEEE 802.3af PoE classification and detection protocols
• Provides comprehensive protection mechanisms including thermal shutdown and overcurrent limiting

Applications

• Power over Ethernet powered devices requiring 802.3af compliance
• Industrial networking equipment operating in harsh environments
