Hi! I am a High school senior and currently enrolled in a PLTW Engineering Design and Development class. In this class we are required to find a problem and then create a product to solve that problem. My team's product is a smart charger that can identify that a cellphone is at 100% and then turn off the power to the device. I don't know much about electrical engineering and would really appreciate the help! I was wondering if there are any circuit boards that have a overvoltage/overcurrent protection and can turn off the power after the phone has reached 100%. I was planning on connecting this component to a female usb port. Thank you for your help!
Thanks
