Abstract
A potential detecting circuit includes an output node, a reference current supplying circuit for supplying a prescribed reference current to the output node, a detection node to which the potential to be detected is applied, and a comparing current supplying circuit, responsive to the potential applied to the detection node, for supplying a comparing current to the output node. The comparing current supplying circuit includes a detection resistance element through which a detection current flows in response to the potential applied to the detection node, and a current mirror circuit responsive to the detection current for controlling supplying the comparing current. When the potential applied to the detection node attains the prescribed detection level, an additional current supplying circuit supplies an addition current to the output node in addition to the comparing current.
