Abstract
A circuit for current measurement and current monitoring in a motor vehicle is provided, with a measuring circuit with a first subtractor circuit, connected to a measuring resistor; an offset circuit, which is connected to the first subtractor circuit in such a way that a first output voltage of the first subtractor circuit is increased by an offset voltage; a second subtractor circuit, which is connected to the offset circuit and the first subtractor circuit in such a way that a second output voltage of the second subtractor circuit is substantially independent of the offset voltage, and a comparator circuit with at least one switching threshold, which is connected to the second subtractor circuit for comparison of the second output voltage with the at least one switching threshold.
