Abstract:
The present invention relates to a driving device. The driving device according to the present invention includes a main transistor that supplies a current to a load by using a power supply, an auxiliary transistor that drops a predetermined voltage of the voltage of the power supply and transmits the dropped voltage to the main transistor in a turn-on state, and a bypass switch that transmits the voltage of the power supply to the main transistor when the auxiliary transistor is turned off.
