Abstract
Disclosed is an apparatus for controlling power of an electronic device, controlled by a touch input. To this end, a power control apparatus for an electronic device according to a preferred embodiment of the present invention is disclosed including a touch sensor for sensing a user's touch by a user's finger or the like, and a temperature sensor for sensing a body temperature detected through the touch. Through such a touch sensor and such a temperature sensor, the power control apparatus senses the touch and body temperature of a user, and controls the power of the electronic device. As a result, even without a separate power button installed on the outside of the electronic device, it becomes possible to control the power of the electronic device.
Claims11
An apparatus for controlling power in an electronic device comprising:
- a temperature sensor having a first input node and a second input node, and outputting voltages according to signals input through the first and the second input nodes, the first input node sensing a body temperature detected through a touch of a user, and the second input node being spaced by a predetermined interval from the first input node;
- two comparators for receiving each of the voltages output from the temperature sensor, each comparator outputting one of high and low signals according to the received voltages;
- a power determination unit for outputting an XOR operation result signal when a high signal is output from one of the comparators;
- a power switching unit for performing a switching operation according to the signal output from the power determination unit;
- and
- a touch sensor for sensing a touch input by the user when a voltage is applied according to the switching operation of the power switching unit, and outputting a power control signal when there is a current change according to the sensed touch input.
