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

Nov 01, 2002, 00:00 ET from Texas Instruments Incorporated

    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.

     --  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.
