Abstract
A circuit and a method for sensing a current flowing from a supply voltage into an electric load are presented. The current sensing circuit comprises a first circuit branch connected between the supply voltage and the electric load, a second circuit branch connected between the supply voltage and ground, and an equalization circuit for equalizing a first voltage drop across a first resistive element and a second voltage drop across a second resistive element and for generating an indication of a current flowing through the second circuit branch.
