Hi Darwin,
Thanks your suggestion but I have a question as below.
If need 802.3af standard compliant, can we use TIDA-00465 reference design or have other suggestion solution?
Thanks.

Eric
Hi Penny,
A debt of gratitude is in order for your review comments. Please find the inline response for those:
1. Please change sense resistor R927 to 255mohm. It impacts the current measurement accuracy.
:- I replaced sense resistor R927 by two parallel…
Hi Ganesh,
Are you looking to be IEEE802.3 compliant on both the input and output? If so, then yes you will need to do as you suggested a PD at the input and PSE like the TPS23861 in TIDA-00465 (or injector) at the output to connect to the other compliant…
Hi Ganesh,
For it to be compliant to the IEEE standard, Box A should have a PSE controller as part of the PD's load powered by the VDD/RTN 48V side of the Box A PD. I recommend using the TPS23861 in auto mode. If a single port design is needed, I recommend…
Hi Sharifa,
If you are looking for an reference design board, you can check the link as below. It is an one port support of PSE controller application.

This design operation is without GUI or MSP430, so it only can works…
Hi Hardy,
I recommend using the below TI Design for a single port 30W PSE application. They can use the VDD-RTN voltage of the PD to power this TI Design. Thanks!
Hi Jerry, the schematic looks okay to me. For the I2C we use the below reference design in automode as well. We pulled SDAI and SCL LOW, then kept SDAO floating. Thanks!
Hi Zoe,
Please see below link for the recommended power reference design. I recommend pairing this with the TPS23861 single port design also below. Thanks!
