Abstract: An integrated semiconductor circuit comprising an output terminal connected to a ground terminal via a series connection of a first switching transistor and a second switching transistor of inverse polarization with respect to the latter, each of said switching transistors having parasitic transistors. Whether the second semiconductor switch means is conducting or not, is dependent on the current flow through a resistor connected between gate and source of the second semiconductor switch means. Whether current flows through this resistor, is dependent on the switching condition of a further switching transistor, which in turn is also determined by the output signal of a comparator circuit by means of which a potential corresponding to the potential present at output terminal is compared to a reference potential.

Abstract: A hysteresis comparator circuit using, for a virtually power-free detection of the voltage value to be subjected to a comparison, a differential stage utilizing on one end load transistors and on the other hand a negative feedback stage and preferably a current mirror stage. The control electrode of one load transistor is fed with the voltage to be used for the comparison. The control electrode of the other load transistor is fed with a reference voltage on the basis of which this load transistor forms a constant load impedance. The second load transistor has a third load transistor connected in parallel thereto, which in response to the output signal of the comparator is either conducting or blocking, so that in accordance with the output signal of the comparator, an additional load impedance is connected in parallel to the impedance of the second load transistor or no such connection is made.
