Abstract
A low resistance high current sense resistor is formed on a semiconductor die using conventional semiconductor processing techniques. The resistor die has one or two resistive layers which are photolithographically divided into a plurality of series and parallel resistor sections connected to first and second main terminals. First and second sense terminals are connected across one or a pattern of plural ones of the resistors to produce an output related to the current between the main terminals. Fusible links permit the trimming of the final resistance value.
