So schlecht scheint die "Kindergarten"-Idee nicht zu sein! IR schreibt:

Zitat:A source follower totem pole is shown in Figure 6. The relative positions of the P- and N-Channel HEXFET Power MOSFETdevices have been interchanged so that both have the load connected to the source. The gate drive signals are now referenced tothe same point that, unfortunately, is neither of the two supply leads.This circuit has an inherent dead-time, as the gate voltage of either device has to decrease below its own threshold before it canexceed the threshold of the other device. This is equivalent to a "break before make" set a contacts, because it is inherentlyimpossible to drive both devices ON simultaneously.
