Electronic – SMD SOT-25 identify component

componentsdamagepcbrepair

Can I ask for help in identifying the following SMD component? Package is SOT-25. Marking is bPCGD .
Probably is voltage detector but I dont know his parameters. It is a component of mainboard IP camera YI YHS3017.
I add photos of the mainboard and a diagram of this component that I was able to measure. Pinuot 3 is connected to a nearby coil, pinout 2 is ground, pinout 5 is voltage from power supply (5V).
I`ve looked in many catalogs but it is probably a unique label of the manufacturer. I suspected it might be the BD5242G but it doesn't match the ground pinouts.

Thanks for your help

I have looked around, and found also your forum post on a elektroda.pl. But looking further on this website with code bP and looking through the few ones with package SOT25/SOT3353 I think the correct component is RT9193. Especially because there is a coil connected to pin 4 or pin 5, my first guess was that it is some kind of voltage regulator.
