Patent ID: 7573287

Claim:
A drive module for driving a load comprising: an output terminal for connecting the load; a first control terminal for applying a first control signal, according to which a circuit arrangement provides a supply voltage having a first or a second voltage level at the output terminal; and a second control terminal for applying a second control signal, wherein the slope of an edge in the event of a level change in the supply voltage being dependent on the second control signal, wherein the circuit arrangement comprises: a first MOS transistor having a control terminal and a load path connected between a terminal for a supply potential and the output terminal; a second MOS transistor having a control terminal and a load path connected between the terminal for the supply potential and the output terminal; a drive circuit to which the first control signal is fed and which has an output connected to the control terminal of the first transistor; and a switching element driven by the second control signal, said switching element being connected between the output of the drive circuit and the control terminal of the second transistor.
