Three standard logic options are offered – • High Current Drive Capability of ±4 A dual-inverting, dual-noninverting, and one-inverting and one-noninverting driver. The thermally enhanced • Unique BiPolar and CMOS True Drive Output 8-pin PowerPAD™ MSOP package (DGN) drastically Stage Provides High Current at MOSFET Miller lowers the thermal resistance to improve long-term Thresholds reliability. It is also offered in the standard SOIC-8 (D) • TTL/CMOS Compatible Inputs Independent of or PDIP-8 (P) packages. Supply Voltage Using a design that inherently minimizes shoot- • 20-ns Typical Rise and 15-ns Typical Fall Times through current, these drivers deliver 4A of current with 1.8-nF Load where it is needed most at the Miller plateau region • Typical Propagation Delay Times of 25 ns with during the MOSFET switching transition. A unique Input Falling and 35 ns with Input Rising BiPolar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at • 4-V to 15-V Supply Voltage low supply voltages. • Dual Outputs Can Be Paralleled for Higher Drive The UCC2742x provides enable (ENB) functions to Current have better control of the operation of the driver • Available in Thermally Enhanced MSOP applications. ENBA and ENBB are implemented on PowerPAD™ Package 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 2 Applications for standard operation. • Switch Mode Power Supplies Device Information(1) • DC/DC Converters PART NUMBER PACKAGE BODY SIZE (NOM) • Motor Controllers SOIC (8) 4.90 mm × 3.91 mm UCC27423 • Line Drivers UCC27424 MSOP-PowerPAD (8) 3.00 mm × 3.00 mm UCC27425 • Class D Switching Amplifiers PDIP (8) 9.81 mm × 6.35 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
