SLUS545D –NOVEMBER 2002–REVISED MAY 2013

Dual 4-A High Speed Low-Side MOSFET Drivers With Enable

Check for Samples: UCC27423, UCC27424, UCC27425

FEATURES

DESCRIPTION

The UCC27423/4/5 family of high-speed dual

•

Industry-Standard Pin-Out

MOSFET drivers can 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. It is also offered in the standard

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

Enable Functions for Each Driver

High Current Drive Capability of ±4A

Unique BiPolar and CMOS True Drive Output

Stage Provides High Current at MOSFET Miller

Thresholds

•

TTL/CMOS Compatible Inputs Independent of

Supply Voltage

Using a design that inherently minimizes shoot-

through current, these drivers deliver 4A 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.

20ns Typical Rise and 15ns Typical Fall Times

with 1.8nF Load

Typical Propagation Delay Times of 25ns with

Input Falling and 35ns with Input Rising

•

4V to 15V Supply Voltage

Dual Outputs Can Be Paralleled for Higher

Drive Current

The UCC27423/4/5 provides enable (ENBL) functions

to have better control of the operation of the driver

applications. ENBA and ENBB are implemented on

pins 1 and 8 which were previously left unused in the

industry standard pin-out. They are internally pulled

up to Vdd for active high logic and can be left open

for standard operation.
