<p>The present invention relates to an MCU power control apparatus with a fail safety function and, more specifically, to an MCU power control apparatus with a fail safety function, the MCU power control apparatus comprising a first control signal generating unit, a regulator unit, a battery power supply control unit, an IGN power supply control unit, an MCU, a logic gate, and a battery voltage monitoring unit. The MCU power control apparatus may improve driving stability and prevent the risk of an accident by providing the fail safety function for preventing the MCU from promptly stopping operation and a control function from suddenly switching into a manual mode when a battery power voltage is not normally supplied due to a failure or defect in a power supply circuit by temporarily supplying an IGN power voltage to the MCU when the battery power voltage is abnormal.</p> |
