Hey---

Either a full or half bridge has the advantage that the FETs are 
self-protecting.  Spikes of either polarity are caught by the body diode 
of one or the other FET.  With a single FET, there is no protection for 
positive-going spikes.  High- and low-side drivers are readily available 
and not hard to use.
