Abstract
A voltage detection circuit includes a first transistor and a first resistor connected in series between a power supply voltage node and a reference voltage node, a second transistor and a second resistor connected in series between the power supply voltage node and the reference voltage node, a third transistor and a third resistor connected in series between the power supply voltage node and the reference voltage node, and a signal generator that outputs a signal corresponding to a voltage of a connection node between the third transistor and the third resistor. The second transistor is first turned on among the first to third transistors and a voltage level of the power supply voltage node increases, turning off the third transistor, and then a current flows through the first transistor and the first resistor. When the third transistor is turned on, the signal generator changes a logic of the signal.
