A circuit arrangement includes a drive circuit is adapted to generate a drive signal at the output dependent on a signal received at a control input, and dependent on a signal received at the first enable input. A first supply voltage circuit is adapted to provide a first supply voltage at output terminals, the output terminals being coupled to the supply terminals of the drive circuit. A second supply voltage circuit adapted to provide a second supply voltage at output terminals, the output terminals being coupled to the supply terminals of the drive circuit. The second supply voltage circuit has a second enable input, and is adapted to generate the second supply voltage dependent on a signal received at the second enable input.
