Texas Instruments introduced today a family of high-speed drivers that delivers 9 amps (A) of peak drive current in an industry standard pin-out. The UCC37321 and UCC37322 can drive the largest of metal-oxide semiconductor field-effect transistors (MOSFETs) in applications that require extreme Miller current, such as switch mode power supplies, DC/DC converters, motor controllers and class-D switching amplifiers. The drivers effectively eliminate the need for additional external circuits, and replace multiple components to reduce space, design complexity and assembly cost. See: power.ti.com/sc02274. Using a design that minimizes shoot-through current, the outputs of these devices can provide high gate drive current where it is most needed at the Miller plateau region during the MOSFET switching transition. A unique hybrid output stage called TrueDrive™ technology, parallels bipolar and MOSFET transistors, and allows efficient current delivery at low supply voltages. With this drive architecture, UCC37321/2 can be used in industry standard 6-A, 9-A and many 12-A driver applications. Latch up and electrostatic discharge protection circuitries are also included. Features: industry-standard pin-out, active high logic function pin, high-peak current drive capability of +/-9A at the miller plateau region using TrueDrive™ technology, efficient constant current sourcing using a unique Bipolar & CMOS output stage, TTL/CMOS compatible inputs independent of supply voltage, 20 ns typical rise and fall times with 10 nF load, typical propagation delay times of 25 ns with input falling and 35 ns with input rising, 4-V to 15-V supply voltage, rated from -40ºC to 105ºC. The UCC37321/2 family products are available now from TI and its authorized distributors in SOIC-8 (D), PDIP-8 (P) and 8-pin MSOP PowerPAD™ (DGN) packaging. The PowerPAD™ package drastically lowers the thermal resistance to extend the temperature operation range and improve the long-term reliability. Suggested resale pricing in quantities of 1,000 units is $.99.
