1. An apparatus, comprising:
an apparatus input to receive a voltage input;
an apparatus output to drive an output metal oxide semiconductor field effect transistor (MOSFET) at least partially based upon the voltage input;
a current source circuit to provide a current source to the apparatus output when the voltage input rises above a first threshold and before the voltage input rises above a second threshold;
a current sink circuit to provide a current sink to the apparatus output when the voltage input falls below the second threshold and before the voltage input reaches the first threshold; and
a voltage clamp circuit to provide a first clamped output voltage to the apparatus output when the voltage input rises above the second threshold and a second clamped output voltage to the apparatus output when the voltage input falls below the first threshold.
