L loup-garou New Member Jan 8, 2009 #1 Hi everybody, in the 7th page of the L298 datasheet , we suggest that the sense resistor be not of a wire wound type, why this particular kind of resistors is excluded ?, do the commun resistors do the work ? http://www.dragonmodz.net/images/resistor.gif thanks for your interest.
