Smart USB plug detection is disclosed. In some embodiments, a battery charger identification chip includes circuitry configured to determine whether an external USB device has been plugged into a USB port of an associated system while the system is in a sleep mode and includes a pin configured to output a control signal indicating whether an external USB device is plugged into the system, wherein when an external USB device is plugged into the system the control signal facilitates powering on a current limit switch that is otherwise powered off during the sleep mode and wherein the current limit switch facilitates regulated delivery of current to the plugged in external USB device.

An apparatus comprising a circuit that may be configured to (i) change a frequency of one or more first signals in response to a second signal and (ii) generate a third signal in response to either the second signal or a predetermined time period expiring.

Method and apparatus to generate clock and control signals for over-clocking recovery in a PLL

A line driver and a method for driving a line are disclosed. The line driver includes a first current device configured to initiate a change in the state of the line and a second current device configured to substantially complete the change. The first current device provides a first current and the second current device provides a second current that is smaller than the first current.
