Abstract
An automatic switch method and apparatus are used to set the output current of a USB by slowly increasing the output current under monitoring the voltage on the USB. If the USB could normally operate until the output current reaches a threshold value, a higher level is set for the output current, otherwise a lower level is set instead. The process may be performed periodically to dynamically determine the output current for the USB.
