Integrated circuit with built-in status monitoring unit and power supply device provided with said integrated circuit

摘要

A integrated circuit includes a plurality of first connection terminals (410) and second connection terminals (420) for receiving an input of electrical signals, a first detection section, a second detection section, a plurality of switches (432), and a switch control section (430). The first detection section is connected to first connection terminals (410) and obtains input electrical signals. The second detection section is connected to second connection terminals (420). Each switch (432) connects adjacent second connection terminals (420) among second connection terminals (420) to each other, and are connected to each other in series. Switch control section (430) controls to turn off switches (432) and allows electrical signals input to second connection terminals (420) to be input to the second detection section, and controls to turn on any switch among switches (432) to bring adjacent second connection terminals (420) into electrical continuity.
