APPLICATIONS

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).
