We have selected TPS23753A IC for 12V/1A POE module Design.
We have one third party POE module in which the similar IC used and below are our observation.
During the power ON, Device slowly turn on the internal hot-swap MOSFET and could not provide load for around 10 Sec.
After this time period, it will provide full load of 13W.
We could not found any detail about in datasheet about this issue.
Please advise, what could be the issue?
We have given 48V input from DC supply direct with out giving signature and detection voltage sequence.
