Patent ID: 7982621

Claim:
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.
