Abstract
A control circuit for controlling the power or bounce of an output driver circuit is disclosed. The control circuit can sense the output voltage and/or the bounce and then adjust the control node voltage of the output driver circuit accordingly. In addition, the output circuit can discharge the output node to a lower voltage level before turning on the output driver circuit.
