Abstract
Current sensing circuits having independently adjustable dual-level trip thresholds for use in hot swap controllers, solid state circuit breakers and other current sensing circuits. The dual-level trip threshold is user-programmable to provide one current level for power-up conditions and another current level for normal operation. The two separate thresholds are also useful during normal operation to monitor both the steady state current and to set a limit on the upper current which should never be exceeded. Various features and alternate embodiments are disclosed.
