  • Publication number: 20210272395
    Abstract: Generally, the current threshold value is set as a fixed value. Therefore, even in a case where an abnormality occurs in the load and the resistance value is small, when the power supply voltage applied to the load is low, the current value is also low, and falls below the threshold value, and there is a possibility that the overcurrent is not detected. In the present invention, by providing a second detection means that detects a load abnormality by calculating the resistance value of the load from information of the power supply voltage applied to the load, in addition to a first detection means that detects an overcurrent state that indicates the load abnormality using only current value information, it is possible to detect an overcurrent indicating an abnormality of the load even when the power supply voltage applied to the load is low.
