Other Parts Discussed in Thread: PMP20859, TPS2372
I am using TPS2373 PD - controller into my gateway power supply board. This board have 2 inputs, out of which 1st is POE power supply (55Vdc) and 2nd one is DC-supply (55Vdc).
Whenever hot-swap takes place from DC-supply to POE power supply, then output supply of my board always drops to 0V for 2-4 sec. in the mean time PD - controller again negotiates power and recovers output supply while vise versa of hot-swap of power supplies shows no drop of output power supply.
Problem : Because of no standby during hot-swap output load always reboots.
Please, suggest the solution if this behavior (no standby during hot-swap) of PD-controller is not normal.
