SLUS334C − AUGUST 1995 − REVISED AUGUST 2004  
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during  
storage or handling to prevent electrostatic damage to the MOS gates.  
DESCRIPTION (CONTINUED)  
Functional improvements have also been implemented in this family. The UC3825 shutdown comparator is now a  
high-speed overcurrent comparator with a threshold of 1.2 V. 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.  
The UC3825A and UC3825B have dual alternating outputs and the same pin configuration of the UC3825. The UC3823A  
and UC3823B outputs operate in phase with duty cycles from zero to less than 100%. The pin configuration of the UC3823A  
and UC3823B is the same as the UC3823 except pin 11 is now an output pin instead of the reference pin to the current  
limit comparator. “A” version parts have UVLO thresholds identical to the original UC3823 and UC3825. The “B” versions  
have UVLO thresholds of 16 V and 10 V, intended for ease of use in off-line applications.  
Consult the application note, The UC3823A,B and UC3825A,B Enhanced Generation of PWM Controllers, (SLUA125) for  
detailed technical and applications information.
