DESCRIPTION
The UCC37321/2 family of high-speed drivers delivers 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).
