<p>A touch sensing device connected to a host processor of an electronic apparatus includes: a touch panel changing an electrical signal by a touch; and a touch sensing unit sensing the change in electrical signal and transmitting the electrical signal to the host processor. The touch sensing unit inputs an ENABLE signal for dropping a voltage or a DISABLE signal for intercepting the voltage to a voltage dropping unit on the basis of an operating status of the host processor or the change in electrical signal. The voltage dropping unit is disposed in the electronic apparatus and drops or intercepts the voltage to be applied to the host processor. According to this configuration, it is possible to reduce the power consumption of the host processor.</p> |
