Title:
SEMICONDUCTOR DEVICE AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/012987
Kind Code:
A1
Abstract:
This semiconductor device is provided with a first semiconductor relay and a second semiconductor relay which are connected to each other in parallel, an input switching circuit which switches the path of the signals inputted to the first and the second semiconductor relay, an output switching circuit which switches the path of the signals outputted from the first and the second semiconductor relay, and a monitoring unit which performs anomaly detection of the first and second semiconductor relay and gives warnings. Further, the device performs one of: a redundancy mode for controlling the input switching circuit so as to share the input of the first and second semiconductor relay in response to a first setting signal from the outside, and controlling the output switching circuit so as to output only one of the first and the second semiconductor relay; and a non-redundancy mode for controlling the input switching circuit and the output switching circuit such that the input and output of the first and second semiconductor relay circuits are different from each other.
