Patent ID: 6972595

Claim:
An electrical circuit assembly, comprising: a node supplying a potential; and an electrical circuit drawing the potential at said node weakly to a given potential when and for so long as said node is drawn to a different potential by an external signal, and drawing the potential at said node strongly to the given potential when and for so long as said node is not drawn to a different potential by an external signal; said electrical circuit having a first component connecting said node to said given potential to which said node is to be drawn by said electrical circuit; said electrical circuit having a second component connecting said node to said given potential to which said node is to be drawn by said electrical circuit; a switching element connected between said second component and said node; wherein said switching element is opened when the potential at said node is below a threshold value; and said switching element is closed when the potential at said node is above said threshold value or above a second threshold value; and a comparator having an output providing an output signal controlling said switching element, said comparator comparing the potential at said node with a threshold voltage.
