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
