Products in this family are solid-state devices used to connect or interrupt the flow of current to a supported load, under the direction of a logic-level control signal that is of itself incapable or unsuitable for supplying the load. They integrate the semiconductor switching device used to interrupt current flow and incorporate additional supporting components/functions such as over-voltage clamping, current limiting, and under-voltage lockouts, which differentiate them from similar IC and discrete components.
