The UCC2732x/UCC3732x 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).
