Abstract

In some embodiments, an apparatus and a system, as well as a method and an article, may operate to transform a first control signal to produce an isolated second control signal, to receive a pair of floating power supply voltages at opposing ends of a totem-pole series of driver metal-oxide semiconductor field-effect transistors (MOSFETs), and to clamp an output of a driver apparatus to one of the pair of floating power supply voltages. The isolated second control signal may operate to control current flow through the driver MOSFETs. Additional apparatus, systems, and methods are described.
