  • Multi-mode charger device
    Patent number: 9030155
    Abstract: Multi-mode charger device for charging portable devices and methods of charging portable devices are described. In an embodiment, a multi-mode charger device has mode blocks respectively associated with modes of operation which are coupled to a switch module. The switch module is for coupling a selected one of the mode blocks to a peripheral bus and to decouple the mode blocks remaining from the peripheral bus. A first mode of the modes of operation is a pass through mode. A second mode of the modes of operation is a first charging mode. A third mode of the modes of operation is a second charging mode. The first charging mode and the second charging mode are different from one another.
