Original PI SC1143DG SOP-8 Control IC Chips for PS5 Power Board
In power circuits, X capacitors are often used to filter out EMI (electromagnetic interference) and smooth DC voltage. When the power is cut off, a high voltage may remain on the X capacitor, which may cause danger to maintenance personnel or equipment. Therefore, the function of the X capacitor discharge chip (such as SC1143DG) is to safely discharge the residual voltage on the X capacitor when the power is turned off, thereby protecting the safety of personnel and equipment.
