Patent ID: 7898294

Claim:
A pre-driver circuit, comprising: an input node coupled to receive an input signal; an output node; a first transistor having a source/drain coupled to the output node and having a control gate; a second transistor; and a third transistor having a source/drain coupled to the output node and having a control gate coupled to a source/drain of the second transistor; wherein when the pre-driver circuit receives an input signal of a first type at the input node, the pre-driver circuit activates the first transistor such that the pre-driver circuit provides a first output signal; wherein when the pre-driver circuit receives an input signal of a second type at the input node, the pre-driver circuit activates the second transistor and the third transistor that together cause the pre-driver circuit to provide a second output signal; wherein the first transistor is deactivated in response to an input signal of the second type; and wherein the control gate of the first transistor is isolated from the source/drain of the second transistor.
