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,
Typical Propagation Delay Times of 25 ns
With Input Falling and 35 ns with Input
Rising
