Abstract
A fault tolerant/failsafe current limit system for shutting down a power supply if an overcurrent condition exists at one or more selected load circuits in a set of load circuits. A current limit circuit couples each selected load circuit to the power supply and includes at least two monitoring circuits for detecting whether the current delivered to the selected load circuit exceeds a preselected limit. The power supply will be shut down unless both monitor circuits agree that the delivered current does not exceed the preselected limit.
