PURPOSE: An initiation circuit designed to prevent error operations of micro computer is provided to enable the micro computer's input voltage to be provided with flexibility when outputting reset signal, designed to initialized the micro computer, to the micro computer's reset terminal. CONSTITUTION: An initiation circuit designed to prevent error operations of micro computer is composed of selection, detection, prevention, and output. Standard voltage selector(100) selects standard voltage and detects the voltage that deviates from the turn-on area while being inputted to the micro computer, or instantly detects whether the voltage returned to the designated area after invading the deviation area. Comparer(110) compares the voltage being inputted to the micro computer to the standard voltage, and if micro computer's input voltage has deviated from the turn-on area, comparer outputs a reset signal that is designed to initialize the micro computer. Voltage converter(120) prevents the voltage rate of the voltage, which is inputted to the micro computer's reset terminal, from being as high as the comparer's output voltage when the voltage destined for micro computer deviates from the turn on area. Charge/discharge circuit department(130) delays the output of comparer, which is designed to instantly increase the reset terminal's voltage, for a fixed time, resets the voltage to the original voltage rate, and outputs the voltage.
