FEATURES

APPLICATIONS

•

Industry-Standard Pin-Out

•

Switch-Mode Power Supplies

DC/DC Converters

High Current-Drive Capability of ±4 A at the

Miller Plateau Region

Motor Controllers

•

Efficient Constant-Current Sourcing Even at

Low Supply Voltages

Line Drivers

Class D Switching Amplifiers

TTL/CMOS Compatible Inputs Independent of

Supply Voltage

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 deliver large peak currents into

capacitive loads. Three standard logic options are

offered — dual-inverting, dual-noninverting, and one-

inverting and one-noninverting driver. The thermally

enhanced 8-pin PowerPAD MSOP package (DGN)

drastically lowers the thermal resistance to improve

long-term reliability. UCC3732x is also offered in the

standard SOIC-8 (D) or PDIP-8 (P) packages.

Typical Propagation-Delay Times of 25 ns with

Input Falling and 35 ns with Input Rising

•

4.5-V to 15-V Supply Voltage

Supply Current of 0.3 mA

Dual Outputs are Paralleled for Higher Drive

Current

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.

•

Available in Thermally Enhanced MSOP

PowerPAD™ Package with 4.7°C/W θ_JC

•

Rated From –40°C to +125°C

TrueDrive™ Output Architecture Using Bipolar

and CMOS Transistors in Parallel
