I’m going to deploy a rechargable battery on my printed circuit board. as the PCB is very small and thin(60mm*60mm*2mm), I’ve decided to put a mobile battery on. but the question is how to implement the charger circuit!
recently I’ve faced the topic usb mobile charger circuit on enginnersgarage but I don’t know whether there is any protection on the designed circuit to prevent extra charging after the battery has fully charged!!!
