3 Description
The UCC2732x-Q1 family of high-speed drivers
delivers 9 A of peak drive current in an industry-
standard pinout. These drivers can drive large
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 (UCC27321-Q1) and noninverting
(UCC27322-Q1).
Using a design that minimizes shoot-through current,
the outputs of these devices 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, UCC2732x-Q1 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 UCC2732x-Q1 provides an
enable (ENBL) function to better control 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.
