The UCC27424P is a Dual 4A MOSFET Driver that can deliver large peak currents into capacitive loads. Three standard logic options are offered - dual-inverting, dual-non inverting and one-inverting and one-non inverting driver. Using a design that inherently minimizes shoot-through current, this driver delivers 4A of current where it is needed most at the Miller plateau region during the MOSFET switching transition. An unique bipolar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply voltages. It 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.
