DESCRIPTION
20-ns Typical Rise and 15-ns Typical Fall
Times with 1.8-nF Load
The UCC37323/4/5 family of high-speed dual MOSFET
drivers can deliver large peak currents into capacitive
loads.Three standard logic options are offered –
dual-inverting, dual-noninverting and one-inverting and
Typical Propagation Delay Times of 25 ns with
Input Falling and 35 ns with Input Rising
one-noninverting driver. The thermally enhanced 8-pin

MSOP package (DGN) drastically lowers
the thermal resistance to improve long-term reliability.
It is also offered in the standard SOIC-8 (D) or PDIP-8
(P) packages.
Dual Outputs Can Be Paralleled for Higher
Drive Current
Available in Thermally Enhanced MSOP
Using a design that inherently minimizes shoot-through
current, these drivers deliver 4-A of current where it is
needed most at the Miller plateau region during the
MOSFET switching transition. A unique BiPolar and
MOSFET hybrid output stage in parallel also allows
efficient current sourcing and sinking at low supply
voltages.
