Overview
TC7258F is an 8-channel blanking control driver IC designed specifically for LED screen line scan screens. It integrates line Hidden circuit, 74HC138 38 decoder and power tube.
TC7258F will open the internal pull-down tube when the power tube is turned off and absorb the residual charge on the row line with a constant current, which can eliminate the smear phenomenon.
It can also improve the caterpillar phenomenon caused by LED leakage and short circuit at the same time.
The unique patented technology of TC7258F can more completely eliminate the ghosting phenomenon, and it is the chip with the best LED screen scanning display effect on the market.
TC7258F adopts SOP-16 package form and integrates anti-burning power tube inside.
