TI's New Family of 9 Amp High-Speed MOSFET Drivers Reduce Space, Design Complexity and Assembly Cost
Drivers Ideal for Power Applications Requiring High Gate Drive Current
DALLAS, Nov. 1 /PRNewswire/ -- Texas Instruments (NYSE: TXN) 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(TM) technology, parallels bipolar and MOSFET transistors, and allows efficient current delivery at low supply voltages. With this drive architecture, UCC37321/2/3 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 +-9 A at the Miller Plateau Region Using TrueDrive(TM) 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 -- Available in Thermally Enhanced MSOP PowerPAD(TM) Package -- Rated From -40 degrees C to 105 degrees C Available Today 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(TM) (DGN) packaging. The PowerPAD(TM) 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.
