Abstract
An output driver capable of reducing a leakage current is provided. In the output driver, a low voltage analog part is connected to a low voltage terminal and generates a mirror current proportional to an inputted current. A high voltage output driver is connected to a high voltage terminal and a current flows through the high voltage output driver when the mirror current flows. A switch selectively connects the low voltage analog part and the high voltage output driver. At least one compensation diode is disposed between the high voltage output driver and the switch.
