Qualified for Automotive Applications
The UCC2742x high-speed dual MOSFET drivers
Industry-Standard Pinout
can deliver large peak currents into capacitive loads.
Enable Functions for Each Driver
Two standard logic options are offered
– dual
inverting and dual noninverting drivers. They are
High Current Drive Capability of
±4 A
offered in the standard SOIC-8 (D) package.
Unique Bipolar and CMOS True Drive Output
Stage Provides High Current at MOSFET Miller
Using
a
design
that
inherently

Supply Voltage
unique bipolar and MOSFET hybrid output stage in
20-ns Typical Rise and 15-ns Typical Fall
parallel also allows efficient current sourcing and
