A current limiting circuit includes a limit current setting unit that sets a value of a limit current for limiting an output current from a driver circuit connected to the current limiting circuit, the limit current value including a first acceptable value and a second acceptable value larger than the first acceptable value; an excess current detecting unit that detects when the output current from the driver circuit exceeds the first acceptable value; and a limit current adjusting unit that replaces the first acceptable value with the second acceptable value in a period when the output current detected by the excess current detecting unit exceeds the first acceptable value. |
