Part Number: TIDA-00465 Hello Team,
Am i correct, that the H6096NL transoformer will be in series with the magnetics that I have directly after my ethernet phy?
If yes, do you have any idea on the transmission loss it will add, eg. how much less cabling…
Part Number: TPS23754 Other Parts Discussed in Thread: TPS23861 , TPS23882 , TIDA-00465 , , TPS23756 Hi Team,
A customer is looking into developing a RFID reader PoE PD with 18W power consumption and max 100MBit/s. Can you check if the following statements…
Part Number: TPS23861 Other Parts Discussed in Thread: TIDA-00465 Hi Team,
When I look at the schematic of TIDA-00465( https://www.ti.com/tool/TIDA-00465 ), I have doubts about below circuits.
1. what's the function of this circuit?
2. why need to choose…
Hello,
We would recommend one of our single port PSE designs, but they use a newer part.
The TIDA-00465 uses a 54V DC input and an LDO to get the 3.3V rail.

The PMP20588 uses a 12VDC or 24V AC input which is then…
Hi Xiaofu,
A couple comments regarding the schematics:
Sense resistors look under rated in power. Please use at least 1/4W 0805 sense resistors.
I don't see where PSE_N1 goes, is there another port in the system?
I don't see a series cap on the other…
Hi Duncan,
Thank you for the wait. These are all the TIDA designs that the team could pull in regards to PoE.

Hi Kohei,
For PSE, we recommend our single port reference design: www.ti.com/.../TIDA-00465
Do you have additional design requirements for your PD? (type, output power, topology, efficiency, etc) I can recommend designs.
Regards,

Hi Chen,
These PoE pass-through designs are becoming common in PoE PD applications. Unfortunately, we do not have a dedicated TI design. However, the solution can be quite simple.
I recommend taking the TPS23754EVM-383 (12V type 2 PD), and adding a…
Hi Andy,
In short, in order to make the TPS23861 switch between AF and AT, you need a microcontroller to let the TPS23861 output AF, AT power at the PSE output.
However, if you know that the third block will always be AF then this might not be necessary…
