TPS23861: TPS23861 inconsistent start up and working

Part Number:TPS23861

Hi Expert,

I am using the TPS23861 for a single port PoE 802.3at adapter. I have a working prototype but the circuit seems to function inconsistently i.e. when we apply power to the circuit it sometimes detects, classifies and applies power to the PD properly but at other times it doesn't perform any of those functions. Can you please help me with this problem.

Thank you.

Regards,

Mikha.
