Abstract
A voltage detection device is provided. The voltage detection device includes a first voltage divider circuit, a comparison circuit, and a second voltage divider circuit. The first voltage divider circuit is configured to receive an input voltage and output a comparison voltage according to the input voltage. The comparison circuit is configured to receive the comparison voltage to compare the comparison voltage with a reference voltage and determine whether to change a trigger signal according to a comparison result. The second voltage divider circuit is configured to receive the input voltage. When the input voltage is greater than or equal to a predetermined voltage value, the second voltage divider circuit and the first voltage dividing circuit form a parallel structure to pull down the comparison voltage.
