3 Description
The UCC27324-Q1 high-speed dual-MOSFET driver can deliver large peak currents into capacitive loads. Using a design that inherently minimizes shootthrough 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.

The device is offered in a standard SOIC-8 (D) package.
