Part Number: TPS23881 Other Parts Discussed in Thread: TIDA-050026-23881 Hi Sir,
the i2c from the SOC and through the isolation IC, but the i2c signal can not be measure at TPS23881 terminal.
may we know what caused it? attached is schematic, please kindly…
Darwin,
Thank you. I took a look at the eval board: https://www.ti.com/tool/TIDA-050026-23881
And I did see that it takes an input and uses another ethernet transformer to inject power. If that works, that is good enough for me.
Many thanks.
Hi user4644112,
The files you got are correct. There are 6 devices and they share the same schematic but we set different A1-A3 resistors to be not populated for different TPS23881 device. If you output the schematic you will get the same PDFs from https…
Hi Edgar,
if i use 1u || 1u || 100n then this is effective over 1uF, but how do you explain this TI reference design that has only 470nF effective capacitance on input?
PSEMTHR24EVM-081 / TIDA-050026 / PSIL081
We expect 100mVpp like on this design

Hi Michael,
Please take a look at TIDA-050026-23882 . It is a 24 port (30W each) system and we have provided turnkey system FW(in MSP430F5234) and customers only need to configure system level parameters such as total number of ports, power budget and…
User6233052,
You have understood correctly. The TPS23880 does not offer autonomous mode (the ability to run without being configured first). You must configure the device through our GUI (which requires a USB2ANY connection OR through use of an MCU (and…

Hi,
I am designing a camera with an embedded Cyclone 10 CX220 FPGA which should be powered over ethernet.
I found this pretty neat solution…
Hi Ufuk,
It is recommended to program the SRAM code into TPS23882 if you want to pass compliance test. You can download SRAM code from TPS23882 mySecure folder(requesting access from http://www.ti.com/product/TPS23882 ). We have an tech note describes…
