Abstract
A voltage monitoring system includes a voltage dividing circuit and a voltage monitoring device. The voltage dividing circuit is configured to divide a power signal to generate an input voltage. The voltage monitoring device includes an input node, a shunt circuit, a first detection circuit and a second detection circuit. The input node receives the input voltage. The shunt circuit is configured to compare the input voltage with a voltage threshold value to selectively operate in a conducted state or a switched-off state, and configured to output a flag signal to indicate the conducted state or the switched-off state of the shunt circuit. The first detection circuit generates a first detection signal corresponding to the input voltage. The second detection circuit generates a second detection signal corresponding to the power signal according to the flag signal and the first detection signal.
