Three standard logic options are • High Current Drive Capability of ±4A offered – dual-inverting, dual-noninverting and one- inverting and one-noninverting driver. The thermally • Unique BiPolar and CMOS True Drive Output enhanced 8-pin PowerPAD™ MSOP package (DGN) Stage Provides High Current at MOSFET Miller drastically lowers the thermal resistance to improve Thresholds long-term reliability. It is also offered in the standard • TTL/CMOS Compatible Inputs Independent of SOIC-8 (D) or PDIP-8 (P) packages. Supply Voltage Using a design that inherently minimizes shoot- • 20ns Typical Rise and 15ns Typical Fall Times through current, these drivers deliver 4A of current with 1.8nF Load where it is needed most at the Miller plateau region • Typical Propagation Delay Times of 25ns with during the MOSFET switching transition. A unique BiPolar and MOSFET hybrid output stage in parallel Input Falling and 35ns with Input Rising also allows efficient current sourcing and sinking at • 4V to 15V Supply Voltage low supply voltages. • Dual Outputs Can Be Paralleled for Higher The UCC27423/4/5 provides enable (ENBL) functions Drive Current to have better control of the operation of the driver • Available in Thermally Enhanced MSOP applications. ENBA and ENBB are implemented on PowerPAD™ Package with 4.7°C/W θJC pins 1 and 8 which were previously left unused in the • Rated From –40°C to 125°C industry standard pin-out. They are internally pulled up to Vdd for active high logic and can be left open for standard operation. APPLICATIONS • Switch Mode Power Supplies BLOCK DIAGRAM • DC/DC Converters • Motor Controllers • Line Drivers • Class D Switching Amplifiers 1 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. 2 PowerPAD is a trademark of Texas Instruments.
