DESCRIPTION  
20-ns Typical Rise and Fall Times with 10-nF  
Load  
The UCC37321/2 family of high-speed drivers deliver  
9 A of peak drive current in an industry standard  
pinout. These drivers can drive the largest of  
MOSFETs for systems requiring extreme Miller  
current due to high dV/dt transitions. This eliminates  
additional external circuits and can replace multiple  
components to reduce space, design complexity and  
assembly cost. Two standard logic options are  
offered, inverting (UCC37321) and noninverting  
(UCC37322).  
Typical Propagation Delay Times of 25 ns  
With Input Falling and 35 ns with Input  
Rising  
4-V to 15-V Supply Voltage  
Available in Thermally Enhanced MSOP  
PowerPAD™ Package With 4.7°C/W θjc  
Rated From –40°C to 105°C  
Pb-Free Finish (NiPdAu) on SOIC-8 and  
PDIP-8 Packages
