Abstract:
A method for operating a current limit power switch for supplying power to a load include activating the power switch to start supplying power to the load; limiting the current drawn by the power switch to a first current limit for a first, fixed duration; after the first, fixed duration, limiting the current drawn by the power switch to a second current limit for a second duration where the second current limit is less than the first current limit; and after the second duration, limiting the current drawn by the power switch to a third current limit where the third current limit is less than the second current limit.
