3 Description
The UCC2732x and UCC3732x family of high-speed dual-MOSFET Drivers deliver 4-A source and 4-A sink peak current to effectively drive MOSFETs where it is needed most at the Miller Plateau Region. A unique Bi Polar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply voltages. Three standard logic options are offered
- dual-inverting, dualnoninverting, and one-inverting and one-noninverting driver. Input thresholds are based on TTL and CMOS and independent of supply voltage and feature wide input hysteresis offering excellent noise immunity. The UCC2732x and UCC3732x family is available in the standard SOIC-8 (D) or PDIP-8 (P) packages as well as the thermally enhanced -8pin Power PAD MSOP package (DGN), drastically lowering thermal resistance to improve long term reliability.
