Abstract
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.
