Abstract: Disclosed is a battery charging circuit having several operating modes include boost and buck mode, and forward and reverse mode. A power train and a current sensing block may share power transistors thus reducing the number of space-consuming power devices in the circuit. The current sensing block may indicate output current based only a sensed input current, and vice versa.

Abstract: Circuitry in an electronic device may be attached to external device, such as a power supply, to receive a voltage at a desired voltage level from the external device. The circuitry may assert one of several electrical configurations on the cabling that electrically connects the portable device to the external device to indicate to the external device a desired voltage level.
