The UCC2732x and UCC3732x family of high-speed
dual-MOSFET Drivers deliver 4-A source and 4-A
sink peak current to effectively drive MOSFETs where
it is needed most at the Miller Plateau Region. A
unique BiPolar and MOSFET hybrid output stage in
parallel also allows efficient current sourcing and
sinking at low supply voltages. Three standard logic
options are offered — dual-inverting, dualnoninverting, and one-inverting and one-noninverting
driver. Input thresholds are based on TTL and CMOS
and independent of supply voltage and feature wide
input hysteresis offering excellent noise immunity.
The UCC2732x and UCC3732x family is available in
the standard SOIC-8 (D) or PDIP-8 (P) packages as
well as the thermally enhanced -8pin PowerPAD
MSOP package (DGN), drastically lowering thermal
resistance to improve long term reliability.
