To enhance status detection accuracy while suppressing an increase in the number of connection terminals, an integrated circuit is provided with a plurality of first connection terminals (410) and second connection terminals (420) that have electrical signals applied thereto, a first detection unit, a second detection unit, a plurality of switches (432), and a switch control unit (430). The first detection unit is connected to the plurality of first connection terminals (410) and acquires applied electrical signals. The second detection unit is connected to the plurality of second connection terminals (420). The plurality of switches (432) connect adjacent second connection terminals (420) from among the plurality of second connection terminals (420) and are connected to each other in series. The switch control unit (430) performs control so as to turn off the plurality of switches (432), apply the electrical signals applied to the plurality of second connection terminals (420) to the second detection unit, and turn on a switch from among the plurality of switches (432) so as to cause current to flow through adjacent second connection terminals (420). |
