Part Number: TPS23841 Hello,
I have general some questions regarding the design of POE injectors. I already understand that we need to use a PSE controller such as TPS23841. However, I have other questions regarding the overall circuits and the needs of…
Part Number: TPS23841 Hello,
I have a question about the TPS23841 datasheet. On page 6 it says the threshold for WD_DIS is 1.5 volts, but on page 9 it says ‘connected to 3.3V’.
Does it need to be 3.3 V or could I drive to 1.8 V from our CPU…

Greetings Nakai-San.
The TPS23841 is, indeed, our only Wide Vin PSE. However, we do not offer software support for this PSE as it is an older generation device.
May I ask what end equipment is requiring the Wide Vin?
Thank you for your local support…
