Abstract
One embodiment of the invention provides a voltage supply control device, as well as a process for the control of the voltage supply of a semiconductor component, which can be operated in at least two different voltage supply modes. The process includes detecting the level of a voltage present at an output connection, which in one case is, a voltage output connection of the semiconductor component. The process also includes operating the semiconductor component in the first or second voltage supply mode, depending on the result of the detection.
