Method and circuit arrangement for driving a piezoelectric actuator

The method for the operating of a piezo-actuator entails providing a first discharge passage (R1) between a first connection (Cp+) and a second operating potential (GND) with a charge state in which a first operating potential is applied to the first connection and the second potential is applied to a second connection. At a determined point in time (t1) during the discharging of the piezo-actuator a second discharge passage (R3) is provided between the second connection and a potential (Unps) which lies between the two operating potentials. An independent claim is included for a circuit arrangement with means to carry out the aforesaid method.
