Monolithically integrated output stage component having an overload protection device

摘要

A monolithically integrated output stage component (10), in particular an MOS output stage, is proposed, which is provided with an output stage element (11), which has a gate connection, source connection and a drain connection, and with means (12) for detecting the drain current. A comparator (14) is provided as the overload protection device, which switches off the output stage element (11) if the current exceeds a value which can be predetermined, it being possible to adjust the current value which can be predetermined as a function of a control input voltage (VI) for the output stage element (11). The current value which can be predetermined, that is to say the drain current switching-off threshold, can be set individually and matched to the respective circumstances in a simple manner by varying the control input voltage. <IMAGE>
