Abstract
An output driver circuit includes an input stage to which an input voltage is applied, and an output stage to which an output voltage is applied, input stage and output stage being connected by at least one supply voltage terminal and/or at least one ground terminal to which at least one parasitic inductance is applied, and the input stage and output stage being configured so that when the difference amount between a potential as a function of the input voltage and a potential as a function of the supply voltage and/or ground voltage exceeds a predefined first threshold value or drops below a predefined second threshold value a flow of current is activated or deactivated respectively in the output stage via the supply voltage terminal(s) and/or the ground terminal(s) which also flows via the parasitic inductance(s). The output driver circuit in includes in addition, a circuit element connected to the input voltage capable of “seeing” or determining whether the input voltage in a predefined interval hovers around a value corresponding to the first threshold value or second threshold value and that, if so, a control signal is generated with which changes in the flow of current in the…
