Abstract: A system for enabling data syncing between a host device and an electronic device includes a first port configured to be coupled to a first electronic device, a second port configured to be coupled to the host device, and a data sync switch coupled to the first port and the second port. The data sync switch is switchable between a first state, in which data communication between the electronic device and the host device is enabled, and a second state, in which data communication between the electronic device and the host device is disabled. The system also includes an authorization device configured to couple to an authorizing physical object and generate an output signal. The data sync switch is in one of the first state and the second state based on the output signal from the authorization device.

Abstract: A charging circuit for charging a portable electronic device includes a port configured to be coupled to the portable electronic device, a power switch coupled to the port and configured to be coupled to a power supply, and a control circuit coupled to the power switch and the port. The power switch is switchable between an open state and a closed state. The control circuit is operable to control the power switch based on an amount of charging current drawn by the portable electronic device through the port.
