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).

Using a design that inherently minimizes shoot-through current, the outputs of these can provide high gate drive current where it is most needed at the Miller plateau region during the MOSFET switching transition. A unique hybrid output stage paralleling bipolar and MOSFET transistors (TrueDrive) allows efficient current delivery at low supply voltages.
