Various embodiments include an input circuit comprising: a pull-up resistor having one end thereof connected to an input terminal; a switch unit for establishing/blocking a connection between the other end of the pull-up resistor and a battery; and a dark current reduction unit connected between the other end of the pull-up resistor and the switch unit, and enabling different current paths to be formed in a normal mode and in a low power mode. The dark current reduction unit enables a current path in the low power mode to have a higher resistance than a current path in the normal mode.
