Part Number: TPS23882
Is the TPS23882 Type-3 2-pair IEEE 802.3bt (30W/15.4W) compliant? Where can I find TPS23882 passing Sifos conformance test reports to be certain?
The TPS23882 is Type-3 2-pair IEEE 802.3bt (30W/15.4W) compliant and has received an interoperability score of 100% on Sifos IEEE 802.3bt 2-pair conformance test suite version 5.1. TI has passing Sifos test reports for the TPS23882 under various configurations. The configuration of the TPS23882 when these reports were generated is shown in the table below:
2-Pair Allocated Power

Memory Utilization: ROM or SRAM Version
GUI Used for Configuration
TPS23882EVM-008 + BOOST-PSEMTHR8-097
N/A – Autonomous operation resistor for 15.4W ( = 124 kΩ) utilized.
N/A - Autonomous operation resistor for 30W ( = 62 kΩ) utilized.

IEEE 802.3bt Interoperability Note
IEEE 802.3bt compliant devices are backwards compatible with IEEE 802.3at and IEEE 802.3af compliant devices. For example, an IEEE 802.3at compliant PD and/or IEEE 802.3af compliant PD will interoperate with an IEEE 802.3bt compliant PSE. TI believes it is advantageous to design with IEEE 802.3bt compliant devices moving forward for 4-Pair and 2-Pair operation due to the benefits that the .bt standard offers over previous standards such as the new MPS signature, autoclass, power demotion, and more.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
