We want to develop a USB- C charger and we need to check the battery charge percentage of the device connected to the USB- C charger. The connected to de USB- C device can be a Smartphone, Tablet, or PC.
In our charger, we’re going to integrate a processor and we need to read the battery percentage of the device that’s being charged
Is it possible to read the battery percentage of the device connected by USB- C? Any ST reference can do this job?
