  • Fault detection for redundant connections
    Patent number: 11808820
    Abstract: A system includes a first connection configured to allow current flow between a first node and a second node through a first transistor when it is enabled, and a first diode configured to allow current flow between the first node and the second node when the first transistor is disabled. A second connection is configured to allow current flow between the first node and the second node through a second transistor when it is enabled, and a second diode configured to allow current flow between the first node and the second node when the second transistor is disabled. A fault detection circuit is configured to test the first connection by detection of current flow on the second connection with the second transistor disabled, and is configured to test the second connection by detection of current flow on the first connection with the first transistor disabled.
