Industry-Standard Pin-Out  
Enable Functions for Each Driver  
High Current Drive Capability of 4 A  
The UCC27423/4/5 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  
Unique BiPolar and CMOS True Drive Output  
Stage Provides High Current at MOSFET  
Miller Thresholds  
one-noninverting driver. The thermally enhanced 8-pin  
TM  
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.

TTL/CMOS Compatible Inputs Independent of  
Supply Voltage  
20-ns Typical Rise and 15-ns Typical Fall  
Times with 1.8-nF Load  
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.  
Typical Propagation Delay Times of 25 ns with  
Input Falling and 35 ns with Input Rising

Available in Thermally Enhanced MSOP  
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.
