Abstract:
1. A system, comprising: driver logic capable of driving a device; pre-driver logic coupled to the driver logic and that drives the driver logic; wherein, if the pre-driver logic receives an input signal of a first type, the pre-driver logic activates a first transistor such that the pre-driver logic provides a first output signal; wherein, if the pre-driver logic receives an input signal of a second type, the pre-driver logic activates a second transistor and a third transistor that together cause the pre-driver logic to provide a second output signal; wherein, if the third transistor is not activated, the pre-driver logic provides said first output signal; and wherein the second transistor is activated only when the third transistor is activated and where the pre-driver logic is outputting a third output signal, the third output signal having an output level between an output level of the first output signal and an output level of the second output signal.
