Summary:To provide a current detection circuit capable of detecting with low current consumption that a prescribed current flows into a current measuring resistor. A current detection circuit is equipped with a reference voltage circuit which has two NMOS transistors having different threshold voltages and a resistor, and generates a reference voltage at the resistor, and a comparison output circuit which is comprised of a PMOS transistor, an NMOS transistor, and a measuring resistor connected in series in a manner similar to a PMOS transistor, an NMOS transistor, and a resistor and outputs a comparison result.
