DUAL 4-A HIGH-SPEED LOW-SIDE MOSFET DRIVERS WITH ENABLE

FEATURES

DESCRIPTION

•

Qualified for Automotive Applications

The UCC2742x high-speed dual MOSFET drivers

can deliver large peak currents into capacitive loads.

Two standard logic options are offered – dual

inverting and dual noninverting drivers. They are

offered in the standard SOIC-8 (D) package.

Industry-Standard Pinout

Enable Functions for Each Driver

High Current Drive Capability of ±4 A

Unique Bipolar and CMOS True Drive Output

Stage Provides High Current at MOSFET Miller

Thresholds

Using

design that inherently minimizes

shoot-through current, these drivers deliver 4-A

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.

•

TTL/CMOS Compatible Inputs Independent of

Supply Voltage

20-ns Typical Rise and 15-ns Typical Fall

Times With 1.8-nF Load

Typical Propagation Delay Times of 25 ns With

Input Falling and 35 ns With Input Rising

The UCC2742x provide 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 pinout. They are internally pulled up

to V_DDfor active-high logic and can be left open for

standard operation.

•

4-V to 15-V Supply Voltage

Dual Outputs Can Be Paralleled for Higher

Drive Current

•

Rated From –40°C to 125°C
