3 Description
The UCC2742x family of high-speed dual MOSFET
drivers can deliver large peak currents into capacitive
loads. Three standard logic options are offered – dualinverting,
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.
Using a design that inherently minimizes shootthrough
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.
The UCC2742x provides enable (ENB) 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.
