Light emitting element driving device, light emitting device, and vehicle

A light emitting element driving device comprising:

• a reset signal generator arranged to generate a reset signal in accordance with current flowing in a load including a series connected body constituted of a plurality of light emitting elements and short-circuiting switches disposed respectively in parallel with the light emitting elements of the series connected body;
• a set signal generator arranged to generate a set signal in accordance with an anode voltage of the load;
• an output voltage supply unit arranged to generate an output voltage from an input voltage in accordance with the reset signal and the set signal so as to supply the output voltage to the load;
• a determination unit arranged to determine whether or not a ground fault due to abnormality may have occurred on the basis of the anode voltage of the load;
• and
• a signal output unit arranged to externally output a signal indicating that a ground fault due to abnormality may have occurred when the determination unit determines that a ground fault due to abnormality may have occurred, wherein
• the output voltage supply unit does not perform generation stop of the output voltage by a trigger of determination by the determination unit that a ground fault due to abnormality may have occurred.
