Abstract
A voltage detection circuit comprises a reference resistor including a terminal for receiving a first voltage; a reference transistor including a control terminal for receiving a second voltage; a comparator, including a first input terminal for receiving a converted voltage and a second input terminal for receiving the second voltage, for generating an output voltage; and a voltage dropping circuit series, comprising a plurality of voltage dropping circuits connected in a series, for converting an input voltage into the converted voltage; wherein the comparator indicates whether the input voltage matches a specific multiple of a voltage difference between the first voltage and the second voltage, and the specific multiple relates to a number of the plurality of voltage dropping circuits.
