DESCRIPTION  
20-ns Typical Rise and 15-ns Typical Fall  
Times with 1.8-nF Load  
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  
Typical Propagation Delay Times of 25 ns with  
Input Falling and 35 ns with Input Rising  
one-noninverting driver. The thermally enhanced 8-pin

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.  
Dual Outputs Can Be Paralleled for Higher  
Drive Current  
Available in Thermally Enhanced MSOP  
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.
