Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the specific suffix 'PWP' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component when designing systems requiring IEEE 802.3at compliance with integrated DC/DC conversion capabilities. Consider the 20-pin HTSSOP package constraints and the 25W power handling capacity relative to thermal management requirements. Evaluate the need for sleep mode functionality and primary side adapter priority against system power budget and efficiency targets compared to non-Green-mode alternatives.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the Texas Instruments TPS2375 series, which encompasses various PoE interface controllers. The TPS23752 specifically distinguishes itself by supporting Type 2 power levels and incorporating green-mode features. It serves as a specialized solution for networked devices requiring efficient power delivery and regulation directly from Ethernet cables.

Power Over Ethernet (PoE) Controllers Replacement Considerations

The TPS23751PWP is a confirmed substitute within the same family, offering similar IEEE 802.3at interface and DC/DC control functions but without the sleep mode feature. Verify package compatibility and functional differences regarding power management modes before substitution.
