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. Functional improvements have also been implemented. The 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 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 UC2825A has dual alternating outputs and the same pin configuration of the UC3825. "A" version parts have UVLO thresholds identical to the original UC3825. See the application report, The UC3823A,B and UC3825A,B Enhanced Generation of PWM Controllers (SLUA125) for detailed technical and application information.
