    摘要： A circuit for detecting, whether a voltage difference is below a desired voltage difference comprises a voltage shift resistor, a current provider and a detection circuit. The current provider provides a current flowing through the voltage shift resistor such that the desired voltage difference across the voltage shift resistor is determined by a reference signal. The detection circuit is configured to compare a first voltage at a first input with a voltage at a second input to obtain a signal. The voltage shift resistor is coupled between a conductor for a second voltage and the second input, such that the voltage at the second input differs from the second voltage by the desired voltage difference, and wherein the detection circuit is configured to provide the signal, such that the signal indicates, whether the voltage difference between the first and the second voltage is below the desired voltage difference.

    摘要： A voltage monitoring arrangement including a number of comparison devices, which corresponds to a prescribed number of voltage ranges, compares the value of an input voltage with a reference voltage and outputs a prescribed signal if the input voltage is within one of the prescribed voltage ranges. The voltage monitoring arrangement has a latch circuit which, when a latch signal is applied, establishes which voltage range the input voltage is currently in when the latch signal is applied, resulting in the arrangement having automatic voltage range reduction. The voltage monitoring arrangement has a monitoring unit which outputs a predetermined signal if the input voltage is outside the voltage range which exists when the latch signal is applied.
