1. A current control system for an electrical connection device, the current control system comprising:
- a first output having a first predetermined protection level related to a first load that may be connected to the first output;
a second output having a second predetermined protection level related to a second load that may be connected to the second output;
a transistor that provides current to the first output and the second output;
a sensor electrically disposed between the transistor and the second output and that generates a sensor signal based on detecting a flow of current to the second output; and
a current control module that receives the sensor signal and that controls the transistor to provide current based on the sensor signal to either the first output at or below the first predetermined protection level or to the second output at or below the second predetermined protection level.

Abstract
A current control system for an electrical connection device generally includes a first output having a first current rating and a second output having a second current rating. A transistor provides current to the first output and the second output. A sensor is electrically disposed between the transistor and the second output and generates a sensor signal based on a flow of current to the second output. A current control module receives the sensor signal and controls the transistor to provide current based on one of the first and the second current rating.

15. A method of controlling current to an electrical connection device, comprising:
-
providing a single transistor that provides current to a first and a second output based on a current threshold; initializing the current threshold to a first predetermined protection level related to a first load that may be connected to the first output; processing a sensor signal that indicates at least one of a presence and an absence of current flow to the second output; and adjusting the current threshold to a second predetermined protection level related to a second load that may be connected to the second output when the sensor signal indicates the presence of current flowing to the second output. - View Dependent Claims (16, 17, 18)
