Hi,
I was reading the application report SLVA306A about the advanced adapter Oring solution using the TPS23753 and I can't seem to find an option where the gate drive continue switching while the adapter is plug/unplug. It seem there is always a time period, the PSE turn ON and the ADP shut OFF, where the gate drive stop.
It seem possible reducing that time OFF by using DVDD, a diode between the VDD and VDD1 as option 2 describe but not keeping the gate running.
Is there a possibility to load with 10mA the input so the MPS is maintain, use an external supply and when that external supply is removed, the gate drive doesn't stop.
Thanks
