Question about si3402 on
Forum
Hello,
I am using the SI3402 chip to use POE. But it does not work properly.
The circuit I have constructed is as follows. POE: SI3402 (non-isolated)
When POE cable is plugged in, it charges for the first time but it becomes impossible to charge soon. I think that the POE side circuit is a problem because I operate normally when only 5V is applied to the charge IC.
Since it is confirmed that 5V is output from the output terminal, it is not a voltage problem.
I attach the schematic that I composed with PDF. Please make sure that there is something strange in my circuit.
Thank you.
