Abstract
A gate driver comprises a level shifter outputting first and second signals; an output switch unit causing a first current flow in an output terminal by a voltage of the first signal in a first section of the driver to charge the output terminal, causing a second current flow by a voltage of the second signal in a second section, and discharging the output terminal depending on the second current. A current sensing unit causes a sensing current flow depending on the voltage of the second signal in the second section and outputting a preset voltage depending on the flow of the sensing current. A feedback unit causes the voltage of the second signal to attain at least a preset level in the second section depending on the preset voltage.
