Abstract:
1. A charging device, comprising: a mode module configured to provide a plurality of charging conditions associated with a plurality of device types and to provide a data communication mode; wherein the plurality of charging conditions is associated with a plurality of charging modes; a switch module coupled to the mode module for selection of either a charging mode of the plurality of charging modes or the data communication mode; wherein the switch module includes first switches and second switches; wherein the switch module is coupled to switch from the first switches to the second switches for the selection of either the charging mode or the data communication mode; control circuitry coupled to provide an interruption in a distribution of power to a peripheral bus; wherein a device type of the plurality of device types is identified by correspondence with the charging mode selected; wherein the control circuitry is configured to re-initiate a charging mode detection loop for charging a portable device responsive to a power-down or low power state of the portable device halting the charging of the portable device; and wherein the interruption is for a duration sufficient to cause the portable device coupled to the charging device via the peripheral bus to initiate a re-detect for switching between the plurality of charging modes.
