Abstract:
Methods, electronic devices and USB charger apparatus are presented for fast USB charging, in which a high voltage master of the device detects a connected high voltage charger and selectively connects a current circuit to source or sink a current to or from one USB cable data signal conductor while providing a non-zero voltage to the other USB cable data signal conductor to configure the charger apparatus to provide charging power at a particular high voltage level above a nominal voltage level.
