PURPOSE: A current value compensation micom circuit at voltage changing is provided to correct an error of an AD conversion process by determining the failure of a regulator. CONSTITUTION: A constant voltage generator(40) receives a voltage reference value. The constant voltage generator outputs a voltage reference value(V REF) to an A / D input channel N(A/DinN) of a MICOM(30). The MICOM determines the change of the power supply voltage inputted from a regulator based on the voltage reference value. The MICOM corrects a detection error of a current value according to the variation of the power voltage. A regulator(10) supplies power to the power terminal of the MICOM. |
