The UCC27322 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.

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. With this drive architecture, UCC27322 can be used in industry standard 6-A, 9-A and many 12-A driver applications. Latch up and ESD protection circuits are also included. Finally, the UCC27322 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 pin-out. It is internally pulled up to VDD for active high logic and can be left open for standard operation.
