UCC27322P (TEXAS INSTRUMENTS)

The UCC27322P is a Single 9A High Speed Low-side MOSFET Driver with Enable that 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. An unique hybrid output stage paralleling bipolar and a MOSFET transistor (TrueDrive) allows efficient current delivery at low supply voltages. With this drive architecture, UCC37322 can be used in industry standard 6, 9 and many 12A driver applications. Latch up and ESD protection circuitries are also included. Finally, the UCC37322 provides an enable (ENBL) function to have better control of the operation of the driver applications.
