DESCRIPTION
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).
