Abstract
The invention is a circuit and method for controlling a high potential at a significant node by controlling the potential at a control input to an electrical device in electrical communication with the significant node. The potential of the control input is controlled by a control circuit. In a first embodiment the control circuit is a potential generator, and in a second embodiment the control circuit is a programmable circuit. The programmable circuit provides a potential at the control input that is directly proportional to a supply potential until a maximum potential is reached at which time the control input is maintained at the maximum potential.
