DEVICE FOR MINIMIZING A LEAKAGE CURRENT, ESPECIALLY CONTROLLING VARIOUS CIRCUITS USING A DC VOLTAGE AS A POWER IN A SITUATION IN WHICH MINIMUM CURRENT CONSUMPTION IS NEEDED

摘要

PURPOSE: A device for minimizing a leakage current is provided to control appropriately various circuits using a DC voltage as a power in a situation in which minimum current consumption is needed like a sleep mode by applying an FET switch, thereby preventing the leakage current. CONSTITUTION: A power unit(210) applies a DC voltage to a power controller(230) for supplying a power to a terminal. A controller(220) activates a power holding signal(PS_HOLD) when a power-on key of a terminal is activated, and inactivates a power holding signal(PS_HOLD) when a power-on key of a terminal is inactivated. The controller(220) generates a shutdown control signal. The power controller(230) receives the power holding signal(PS_HOLD) and the shutdown control signal, and applies/intercepts a route of the DC voltage applied from the power unit(210) to an audio amplifier or a motor driver according to the power holding signal(PS_HOLD) and the shutdown control signal.
