The invention relates to a semiconductor integrated circuit device, a motor system and a vehicle. An object of the present disclosure is to provide a semiconductor integrated circuit device capable of expanding an appropriate range of an external power supply voltage. A semiconductor integrated circuit device according to the present disclosure includes: a first power supply terminal configured to receive a first voltage; a second power supply terminal configured to receive a second voltage; an internal power supply circuit; and a selection circuit configured to select whether to supply the first voltage to the internal power supply circuit or to supply the second voltage to the internal power supply circuit on the basis of a comparison result between either the first voltage or the second voltage and a reference voltage. The second voltage is lower than the first voltage when a current flows through the second power supply terminal.

    本揭露涉及半导体集成电路装置、电动机系统及车辆。本揭露的目的在于提供一种能够扩大外部电源电压的适当范围的半导体集成电路装置。本揭露的半导体集成电路装置具备:第1电源端子,构成为接收第1电压;第2电源端子,构成为接收第2电压;内部电源电路;及选择电路,构成为根据所述第1电压或所述第2电压的任一个与基准电压的比较结果,选择是向所述内部电源电路供给所述第1电压还是向所述内部电源电路供给所述第2电压。所述第2电压是在电流流动于所述第2电源端子时低于所述第1电压的电压。
