Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 20-HTSSOP package dimensions align with the target PCB footprint. Ensure compatibility with the required operating temperature range of -40°C to +125°C for the intended environment. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component for designs requiring integrated PoE classification and DC/DC conversion in a single package. It is suitable for applications needing support for 802.3at Type 2 power levels. Consider the thermal performance of the HTSSOP package when designing heat dissipation paths. Evaluate the need for Green-mode efficiency improvements against system load profiles.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the Texas Instruments TPS2375x series of PoE controllers.
