Title:
SEMICONDUCTOR DEVICE, TEMPERATURE DETECTION SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/209544
Kind Code:
A1
Abstract:
This semiconductor device comprises: a power element; a drive circuit configured to drive the power element; and a temperature detection circuit configured to be able to detect a temperature of 0ºC or lower. The temperature detection circuit is configured to generate and output, on the basis of a voltage signal which depends on temperature, a detection signal having a lower temperature change rate than that of the voltage signal.
