Abstract: An apparatus for driving a touchpad of a portable terminal including a second control unit controlling the touchpad in an active mode is provided. The apparatus includes a sensor unit for generating interrupt signals when pressure on the touchpad is sensed, a first control unit for outputting activating signals to activate the second control unit when the interrupt signals are input and a switching unit for transmitting the interrupt signals generated from the sensor unit to the first control unit when the second control unit is in an inactive mode. Accordingly, even though the multimedia processor embedded in the portable terminal is in an inactive mode, the multimedia processor is activated when a user presses the touchpad, thereby making it possible to process signals input by touching the touchpad, particularly, to keep the user interface.
