PURPOSE: A power supplying circuit is provided to prevent heat accumulation in a voltage transmission unit by stopping the transmission operation of the voltage transmission unit. CONSTITUTION: A voltage signal transmitting unit(100) transmits a voltage signal inputted through an input terminal to an output terminal. A feedback circuit receives the change level of a voltage which is outputted through an output terminal. A voltage transmission protective circuit(400) controls the operation of the voltage signal transmitting unit to prevent heat which is generated from the voltage signal transmitting unit. An output terminal sensor(410) senses and transfers the level of an output voltage. |
