Abstract
A method for operating an output stage for a piezoactuator includes checking, during an operating phase, in response to the undershooting of a current for the piezoactuator below a setpoint current, whether a point in time for the undershooting lies outside or within a time window. A subsequent current pulse is controlled via the setpoint current if the point in time is located outside the time window, and the subsequent current pulse is controlled via a turn-on time if the point in time is located within the time window.
