Also have a look at National.  They have a new current sense chip (high
side and low side available) that measures 7 A.  It has an internal sense
resistor in the milliohms.  It outputs a PWM signal that is proportional
to the current (with 50% representing zero current and deviation from 50%
representing negative and positive current).  I'm looking at using it as
part of a "pwer tracker" for charging batteries from solar panels.
