UCC27325

双 4A 峰值高速低侧电源 MOSFET 驱动器

The UCC2732x and UCC3732x family of high-speed dual-MOSFET Drivers deliver large peak currents into capacitive loads. Three standard logic options are offered – dual-inverting, dual-noninverting, and one-inverting and one-noninverting driver. The thermally enhanced 8-pin PowerPAD MSOP package DGN drastically lowers the thermal resistance to improve long-term reliability. UCC2732x and UCC3732x is also offered in the standard SOIC-8 D or PDIP-8 P packages.

Using a design that inherently minimizes shoot-through current, these drivers deliver 4 A of current where it is needed most at the Miller plateau region during the MOSFET switching transition. A unique BiPolar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply voltages.
