Abstract
A switching system includes a microcontroller that provides a powering signal to a solid state switch, such as a field effect transistor (FET). A powering signal from the microcontroller preferably is amplified using a charge pump to triple the magnitude of the signal from the microcontroller to provide a sufficient voltage to operate the gate of the FET. The microcontroller preferably provides the powering signal at least several cycles during a selected time period on a repeated, cyclical basis. During times when the controller is not providing the powering signal to operate the gate of the FET, the controller is free to perform other functions. Various other features, including over current monitoring are disclosed.
