Three standard logic options are offered - dualinverting, dual-noninverting, and one-inverting and one-noninverting driver. The thermally enhanced 8pin Power PAD™ MSOP package (DGN) drastically lowers the thermal resistance to improve long-term reliability. It is also offered in the standard SOIC-8 (D) or PDIP-8 (P) packages. Using a design that inherently minimizes shootthrough current, these drivers deliver 4A of current where it is needed most at the Miller plateau region during the MOSFET switching transition. A unique Bi Polar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply...
