Abstract
A voltage monitoring device for monitoring two different supply voltages to be received by an electronic component. The monitoring device has a ratiometrically operating analog/digital converter, whose reference input is supplied with the larger supply voltage and whose measurement input is supplied with the smaller supply voltage. An output signal of the analog/digital converter is supplied to a window comparator in which the output signal is compared with predetermined limit values. A reset signal for the electronic component is produced if the output signal is greater than the upper limit value or less than the lower limit value.
