Part Number: TPS2375-1 Tool/software: Hi team,
The PG pin of the TPS2375PWR-1 is an open-drain output. If the PG output is not being used, is it OK to leave it open without inserting a pull-up resistor?
Thank you for your help.

Taito…
Part Number: TPS2375-1 I need to hold up the incoming IEEE 802.3af PD power bus during 300ms power interruptions, avoiding a PoE re-handshake.
Theoretically, if I have a large cap in the PD that slowly charges up to the incoming bus potential (48VDC…

I'm designing a PoE device that should be powered either by the PoE connector or a DC adaptor (prefer 12V)
The required output DC voltage is…
Other Parts Discussed in Thread: TPS2375EVM Hi,
I have let the reference design found in www.ti.com/.../tps2375-1.pdf (page 1) made as part of a PoE application. Triple-checked everything, but this part doesn't work.
Even the detection phase goes…
I have attached the board schematic below. I had designed it based on the TPS2375-1 datasheet. The scope trace had Ch1 between +Vin and -Vin on the DC/DC converter. CH2 was not connected.
POE_VP and POE_VN is supplied directly from an RJ-45 jack with…

I have an idea of using TPS2375-1 in my board, which require ethernet data transfer too. i'm using pic18f67j60. i choose h1102nl isolation transformer from…
Other Parts Discussed in Thread: TM4C1294NCPDT Hi, I am trying to make a PoE PD (that I designed) work. It has:
TPS2375PW-1 as PoE controller
HX2019FNL as ethernet transformer
TM4C1294NCPDT as microcontroller
The device side of HX2019FNL was…
First of all, do you mean the TPS2375 1 EVM-104 (TPS2375 0 only has -107 and -108)?
You can adjust output voltage by changing the lower resistor of the error amp feedback divider. As you mentioned, the rest of the circuit should be re-evaluated as well…
Thanks. In the next iteration I will try to use the PG. However the issue related to something different. I am still wondering how it is working on a prototype which was build before and it is not working on the new design... If I remove the load circuit…
