Other Parts Discussed in Thread: TPS23861,
Hi,
we are using TPS2379 for 802.3at POE PD or our product along with TPS23861 PSE.
TPS23861 PSE works fine, but we are having an issue with TPS2379.
We based our design on TPS2379EVM-106 but once connected TPS23861 will read the resistance at 31k which is outside of the 19-26.5k range.
We are not sure why is it happening as we use a 24.9k detection resistor with a 63.4-ohm classification one.
Any suggestions are welcome.
Regards
Robert
