  • RE: TPS23841: POE Injector (PSE) Voltage level, Signal Injection, Isolation

    Resolved
    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.

  • RE: TPS23880: Why every PSE chips share same I2C address in TPS23881EVM-083?

    Resolved
    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…

    Resolved
    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…
