1. A circuit control device for controlling power consumption of a plurality of circuit units at least including a first circuit unit and a second circuit unit disposed near the first circuit unit, wherein each of the plurality of circuit units is connected to the circuit control device, the circuit control device comprising:
a monitoring unit configured to monitor whether a detection temperature of each of the plurality of circuit units meets a predetermined overheat condition and whether a detection temperature of an overheated circuit unit meeting the overheat condition, among the plurality of circuit units, meets a predetermined overheat recovery condition; and an overheat protection unit configured to execute an overheat protection operation when the overheat condition is met in any one of the plurality of circuit units, and to stop the overheat protection operation when the overheat recovery condition is met, wherein the overheat protection unit is configured to execute the overheat protection operation to reduce power consumption of the first circuit unit when the overheat condition is met in the first circuit unit, and to reduce power consumption of the second circuit unit when the overheat recovery condition is not met after reducing the power consumption of the first circuit unit, and wherein the overheat protection unit is configured to execute the overheat protection operation to reduce the power consumption of the second circuit unit when the overheat condition is met in the second circuit unit, and to reduce the power consumption of the first circuit unit when the overheat recovery condition is not met after reducing the power consumption of the second circuit unit.
