Procurement Notes

Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm the presence of the G4 suffix indicating lead-free compliance and RoHS adherence. Ensure the 8-TSSOP package matches your PCB footprint requirements. Validate that the specific revision aligns with your design's thermal and electrical constraints before finalizing procurement.

Selection Notes

Select this component for designs requiring a compact, single-channel solution for 802.3af powered devices. The integrated switch reduces external component count compared to discrete solutions. Consider the 8-TSSOP package size for space-constrained layouts. Ensure the system can accommodate the specified 405 mA current limit and 12.95 W power ceiling during normal operation.
