Three standard logic options are • Typical Propagation-Delay Times of 25 ns with offered — dual-inverting, dual-noninverting, and one- Input Falling and 35 ns with Input Rising inverting and one-noninverting driver. The thermally • 4.5-V to 15-V Supply Voltage enhanced 8-pin PowerPAD MSOP package (DGN) • Supply Current of 0.3 mA drastically lowers the thermal resistance to improve long-term reliability. UCC3732x is also offered in the • Dual Outputs are Paralleled for Higher Drive standard SOIC-8 (D) or PDIP-8 (P) packages. Current Using a design that inherently minimizes shoot- • Available in Thermally Enhanced MSOP through current, these drivers deliver 4-A of current PowerPAD™ Package with 4.7°C/W θJC where it is needed most at the Miller plateau region • Rated From –40°C to +125°C during the MOSFET switching transition. A unique • TrueDrive™ Output Architecture Using Bipolar BiPolar and MOSFET hybrid output stage in parallel and CMOS Transistors in Parallel also allows efficient current sourcing and sinking at low supply voltages.
