Abstract: An improved charger and charging system for an electronic device is provided. The charger includes a power delivery controller configured to determine which pins of a USB Type-C connector are used for charging. The power delivery controller is capable of designating pins other than the VBUS pin for charging, thereby distributing the current for charging an electronic device more efficiently.
