SEMICONDUCTOR DEVICE AND VEHICLE-MOUNTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/022022
Kind Code:
A1
Abstract:
A first circuit 110 has a predetermined function and produces an output S1 having a small dependence on a predetermined operation condition COND. A second circuit 120 has the same function as the first circuit 110 and produces an output having a large dependence on the predetermined operation condition COND. A main circuit 130 operates in accordance with the output S1 of the first circuit 110 when the first circuit 110 is normal. The main circuit 130 is capable of generating a detection signal S3 indicating the predetermined operation condition COND, on the basis of the relative relationship between the output S1 of the first circuit 110 and the output S2 of the second circuit 120.
