Patent ID: 8438406

Claim:
A semiconductor integrated circuit comprising: first and second external terminals that receive an external power supply voltage; an internal power supply line that is coupled to the first and second external terminals; a first transistor that is coupled between the first external terminal and the internal power supply line; a second transistor that is coupled between the second external terminal and the internal power supply line; a first monitor line that is coupled to a first node of the internal power supply line; a second monitor line that is coupled to a second node of the internal power supply line, the second node being different from the first node; and a controller that is coupled to the first and second monitor lines, the controller outputting a control signal corresponding to potentials of the first and second monitor lines to the first and second transistors, wherein, in a plane including the first external terminal, the second external terminal and the controller, the controller is formed on a perpendicular bisector of an imaginary line connecting the first external terminal with the second external terminal.
