Output driver for an integrated circuit and method for driving an output driver

摘要

One embodiment of the invention provides an output driver for an integrated circuit. The output driver has a driver circuit for driving an input signal onto an output line. The driver circuit is dimensioned in such a way as to supply a current intensity dependent on the input signal to be driven and/or a potential dependent on the input signal to be driven on the output line. The current value and/or the potential value lie in a current intensity range and/or potential range defined by a predetermined specification. The driver strength of the driver circuit may be set in accordance with a control signal. A measuring circuit is provided to measure the current intensity of the current flowing on the output line and/or the potential of the output line. A control circuit serves for setting the driver strength of the driver circuit so that the potential on the output line is set to a potential value and/or the current intensity is set to a current value, wherein the set potential value and the set current value may lie in a lower power range of the current intensity range and/or potential range prescribed by the specification.
