ABSTRACT:
To identify a fault state, for example, a break in a supply line, while maintaining operational reliability, a circuit configuration for identifying a fault state includes a first transistor of a normally on type having a voltage that pinches off its channel at a control input in a normal operating state and the channel of the transistor having low impedance in a fault state. As a result, preferably, the output of a linear amplifier stage can be connected to the intact potential in the event of a break in the supply line.
