Abstract
At least one of the disclosed systems includes driver logic that is capable of driving a device and pre-driver logic coupled to the driver logic and that drives the driver logic. 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 an output signal. 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 different output signal. If the third transistor is not activated, the pre-driver logic provides the output signal.
