DESCRIPTION
20-ns Typical Rise and Fall Times with 10-nF
Load
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).
Typical Propagation Delay Times of 25 ns
With Input Falling and 35 ns with Input
Rising
