ABSTRACT:
A circuit arrangement (1) has a first circuit block (2) operating at a first supply voltage and a second circuit block (3) operating at a second supply voltage. The first circuit block (2) is coupled to the second circuit block (3) by a voltage level shifting unit (4) in order to transmit a first activation or deactivation signal to the second circuit block (3). It likewise has a voltage level detector (5) which operates at the second supply voltage and is coupled to the voltage level shifting unit (4) and which can be supplied with the first supply voltage, and which is set up such that it outputs a first control signal if the voltage level of the first supply voltage is below a threshold value. The voltage level shifting unit (4) transmits the first deactivation signal to the second circuit block (3) when the voltage level detector (5) outputs the first control signal.
