Voltage monitoring circuit having an analog reset signal generator to generate a reset signal and coupled to a voltage to be monitored; first register to store a first state bit and coupled to the voltage to be monitored; second register connected in parallel to the first register, redundant to the first register, to store a second state bit, and coupled to the voltage to be monitored; logic coupled to the first and second registers and to determine a state control signal from the first and second state bits, and a second reset signal; and OR logic to receive the following signals on the input side and process them with one another according to an OR operation: a first reset signal generated by the analog reset signal generator and the second reset signal, so that a reset control signal is generated and fed to reset inputs of the registers.
