Semiconductor integrated circuit device, motor system and vehicle

Abstract

The present disclosure provides a semiconductor integrated circuit device. The semiconductor integrated circuit device 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 supplying the first voltage to the internal power supply circuit or supplying the second voltage to the internal power supply circuit according to a comparison result between the first voltage and a reference voltage or the second voltage and the reference voltage. The second voltage is a voltage lower than the first voltage and during a current flowing through the second power supply terminal.
