LM5073MH

Overview

The LM5073MH/NOPB is a Power over Ethernet (PoE) controller designed for IEEE 802.3af compliant Powered Devices (PD). It operates within a supply voltage range of 9V to 70V and supports a maximum power dissipation of 12.95 W. The device integrates internal switches and functions as a single-channel controller housed in a 14-HTSSOP package. It is rated for an operating temperature range from -40°C to 125°C with a typical supply current of 2mA.

Feature Summary

• Complies with IEEE 802.3af PoE standards for Powered Device applications
• Integrates internal power switches to reduce external component count
• Supports wide input voltage operation suitable for PoE interfaces

Applications

• IEEE 802.3af Powered Device implementations
• Single-channel PoE interface circuits
• Network equipment requiring integrated PD control

Procurement Notes

Verify the specific suffix, such as NOPB, against the datasheet to confirm lead-free status and RoHS compliance. Confirm the package designation matches the required HTSSOP footprint. Check official Texas Instruments documentation for the most recent lifecycle status, as this part may be discontinued or subject to product change notices.

Selection Notes

Select this component for designs strictly adhering to the 802.3af standard. Ensure the application requires a single channel and can accommodate the 14-pin HTSSOP package dimensions. Verify that the system power budget remains within the 12.95 W maximum limit and that the operating environment falls within the specified temperature range.
