Hi Jonas,
Please check the TPS23861 reference code training videos here: www.ti.com/.../support
For how to run the code with TPS23861EVM, please check TPS23861EVM-612 EVM user's guide: www.ti.com/.../sluuay8e.pdf.
I will work with our digital marketing…
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…
Thanks for quick response,
Previously you have suggested TPS23861EVM-612 for our POE design using TPS23754, By using this can we test initially?
How POE signature Detection,classification and power delivered to our PD.
Is that board will provide 48V…
Hi BJ,
Your understanding is correct. In order to deliver high power(>30W), it is better to use 4 pair. On TPS23861EVM-612 we have two 4 pair ports. We connect first PSE channel to pair 12&36 and second channel to pair 45&78. Schematic can be found in…

Hi Patrick,
Please check TPS23861EVM-612 schematic. The RJ45's ground is the same as the VPWR ground. But there's no voltage on the RJ45 port. the voltage on the port is depending on the voltage between pair 12 and 36, or pair 45 and 78. So only when…
Hi Darren,
Please see my answers inline below.
1.how the TPS23861 work mechanism?
[Penny]TPS23861 has 4 modes: Off, auto, semi auto and manual mode. Please refer to TPS23861 datasheet section 7.4 for more details.
2.that's the function of SDAI and SDAO…
Part Number: TPS2372 Other Parts Discussed in Thread: TPS54560 , , TPS23861 , TPS23861EVM-612 , TIDA-01463 We've had a board developed for us that uses TPS2372 as the PD interface. This then supplies power to a tps54560 switcher set to supply 12V at 2A. 3x…
Each port has the highest current limit at 920mA. Assuming the port voltage is 57V (maximum according to IEEE standard), the max power of each port is 57V * 0.92A = 52.44W.
If you are looking for high power solutions (ex 60W) with TPS23861, UPoE solution…
Hi Ikon,
The TPS23861EVM-612 can not support low voltage power supply which is just your case. The voltage needed to open the port is higher than 24V.
And also there is diode voltage drop. That's why what you measured is higher.
The proper use of…
