Abstract: An integrated circuit is configured to be coupled to a current sensing element and a set resistor having a resistance Rset. The integrated circuit comprises a sense resistor having a resistance Rsense. The sense resistor is coupled to an input of the integrated circuit such that a first sensed current from the current sensing element flows through the sense resistor. The integrated circuit also comprises a reference resistor having a resistance Rreference which is a fixed multiple of Rsense; and circuitry configured to produce an output current such that the value of the output current is proportional to a value of Rset and a fixed ratio between Rsense and Rreference.
