In this case, when the micro USB 130 and the micro USB 230 are coupled, the terminal (D + terminal) of the LDO regulator 140 is short-circuited and the operation of the LDO regulator 140 is disabled. State or stopped state and the power supply VDD supply operation to the control unit 150 is stopped. Therefore, the temperature measuring unit stops the temperature measurement operation and performs only the charging operation with respect to the battery 110. [ In this case, the temperature measuring unit stops the temperature measurement operation without a separate power switch.
