Functional improvements have also been implemented in this family. The
UC2823A,UC2823B/UC2825A,UC2825B pdf ,datasheet shutdown comparator is now a high-speed overcurrent comparator with
a threshold of 1.2V. The overcurrent comparator sets a latch that ensures full
discharge of the soft start capacitor before allowing a restart. While the fault latch
is set, the outputs are in the low state. In the event of continuous faults, the soft
start capacitor is fully charged before discharge to insure that the fault frequency
does not exceed the designed soft start period. The UC3825 Clock pin has become
CLK/LEB. This pin combines the functions of clock output and leading
edge blanking adjustment and has been buffered for easier interfacing.
