Abstract:
1. An output driver circuit comprising: an in put stage for recieving an input voltage; an output stage providing an output voltage, said input stage and output stage being connected to a supply voltage terminal; a ground terminal to which a parasitic inductance element is formed; said input stage and output stage being configured so that when the difference amount between a potential as a function of said input voltage and a potential as a function of a supply voltage at the supply voltage terminal or a ground voltage at the ground terminal exceeds a predefined first threshold value or drops below a predefined second threshold value, a flow of current is activated or deactivated, respectively, in said output stage via said supply voltage terminal which also flows via said parasitic inductance element wherein input stage comprises a determining circuit connected to said input voltage to determine whether said input voltage in a predefined interval approximates a value corresponding to said first threshold value or second threshold value and that, if so, a control signal is generated which changes the flow of current in said output stage and is reduced until said input voltage is outside of said predefined interval.
