PYRO-FUSE CIRCUIT
Apparatus and method for controlling a pyro-fuse. A pyro-fuse control system includes a current sensing circuit and a diagnostic circuit. The current sensing circuit is configured to determine whether the current flowing in conductor exceeds a threshold current. The diagnostic circuit is coupled to the current sensing circuit. The diagnostic circuit is configured to determine whether an indication of current exceeding the threshold current generated by the current sensing circuit is caused by current flowing the conductor and is not caused by a fault in the current sensing circuit.
Method and device for protecting an electrical architecture
A method is for protecting an electrical architecture including a protective device provided with a protective fuse capable of melting in a deteriorated mode of operation during which a breaking current having an amperage greater than a threshold is flowing through the architecture.
