Overview
TC7258EN (with dots) is an 8-channel blanking control driver IC specially designed for LED screen line scan screens.
It becomes a line blanking circuit, 74HC138 38 decoder and power tube.
TC7258EN (with dot) when the power tube is turned off, the internal pull-down tube will open and absorb the residual charge on the line with a constant current, which can dissipate In addition to the smear phenomenon, it can also improve the caterpillar phenomenon caused by LED leakage and short circuit.
The unique patented technology of TC7258EN (with dots) can more completely eliminate the ghost phenomenon, which is the best LED screen scanning display effect on the market Chip.
TC7258EN (with dots) adopts SOP-16 package form, and integrates a burn-proof power tube inside.
