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).

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 theMiller 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. With this drive architecture, UCC3732x can be used in industry standard 6-A, 9-A and many 12-A driver applications. Latch up and ESD protection circuitries are also included. Finally, the UCC3732x provides an enable (ENBL) function to have better control of the operation of the driver applications. ENBL is implemented on pin 3, which was previously left unused in the industry standard pinout. It is internally pulled up to VDD for active high logic and can be left open for standard operation.

In addition to the 8-pin SOIC (D) and 8-pin PDIP (P) package offerings, the UCC3732x also comes in the thermally enhanced but tiny 8-pin MSOP PowerPAD™ (DGN) package. The PowerPAD package drastically lowers the thermal resistance to extend the temperature operation range and improve the long-term reliability.
