Hello support!
We have designed board with TLK105L.
After transformer we have dc source for a PoE divices. So when I try to connect some poe load for example uap-ac-lr (wirless acess point) everithing work is good.
Also we have power n-chanel key on minus 48v dc source. I close the key(Because we don't need a power) and try to connect my board to local net.
But when I try to connect Des1024d to the TLK105L I see the spark. TLK105L start to heating and then I see a short circuit between pin 12 and pin 33.
Like you understood the TLK105L doesn't work after that.
How can I send you the sheme in direct???
BR,
Oleg
