ABSTRACT:
A circuit arrangement for the defined discharge of a capacitive load includes a first connecting terminal for connection of the load, a second connecting terminal for application of a predetermined potential, and a third connecting terminal for application of a discharge signal. The circuit arrangement further includes a first switching element, having a load path and a control connection, the load path of which is connected between the first and second connecting terminals and a second switching element, having a load path and a control connection, the load path of which is connected between the first connecting terminal and a terminal for reference potential. The first switching element is driven in a manner dependent on a switching state of the second switching element. The second switching element is driven by a drive circuit to which the discharge signal is fed and which includes a comparator arrangement.
