DESCRIPTION/ORDERING INFORMATION

The UCC27423 and UCC27424 high-speed MOSFET drivers can deliver large peak currents into capacitive

loads. Two standard logic options are offered – dual inverting and dual noninverting drivers. The UCC27424

thermally enhanced 8-pin PowerPAD™ MSOP package (DGN) drastically lowers the thermal resistance to

improve long-term reliability. The UCC27423 is offered in a standard SOIC-8 (D) package.

Using a design that inherently minimizes shoot-through current, this driver delivers 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 UCC27423 and UCC27424 provide enable (ENB) functions to better control the operation of the driver

applications. ENBA and ENBB are implemented on pins 1 and 8, which previously were left unused in the

industry-standard pinout. ENBA and ENBB are pulled up internally to V_DDfor active-high logic and can be left

open for standard operation.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
