Dual 4 A Peak High Speed Low-Side Power MOSFET Drivers (Rev. D)
Texas Instruments

Description
The UCC37323/4/5 family of high-speed dual MOSFET drivers can 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. It 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.
Features
Industry-Standard Pin-Out High Current Drive Capability of 4 A at the Miller Plateau Region Efficient Constant Current Sourcing Even at Low Supply Voltages TTL/CMOS Compatible Inputs Independent of Supply Voltage 20-ns Typical Rise and 15-ns Typical Fall Times with 1.8-nF Load Typical Propagation Delay Times of 25 ns with Input Falling and 35 ns with Input Rising 4-V to 15-V Supply Voltage Supply Current of 0.3 mA Dual Outputs Can Be Paralleled for Higher Drive Current Available in Thermally Enhanced MSOP PowerPAD? Package with 4.7C/W jc Rated From -40C to 85C TrueDrive Output Architecture Using Bipolar and CMOS Transistors in Parallel APPLICATIONS Switch Mode Power Supplies DC/DC Converters Motor Controllers Line Drivers Class D Switching Amplifiers PowerPAD is a trademark of Texas Instruments.
