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  
a
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 VDD for 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
