Description

DESCRIPTION
The UCC37321/2 family of high-speed drivers deliver 9 A of peak drive current in an industry
standard pinout. These drivers can drive the largest of MOSFETs for systems requiring extreme Miller current due to high dV/dt transitions. This eliminates additional external
circuits and can replace multiple components to reduce space, design complexity and assembly
cost. Two standard logic options are offered, inverting (UCC37321) and noninverting(UCC37322).
FEATURES
Industry-Standard Pin-Out With Addition of Enable Funtion
High-Peak Current Drive Capability of ±9 A at the Miller Plateau Region Using TrueDrive
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 PowerPADTMPackage With 4.7°C/W θjc
Rated From –40°C to 105°C
Pb-Free Finish (NiPdAu) on SOIC-8 and PDIP-8 Packages
APPLICATIONS
Switch Mode Power Supplies
DC/DC Converters
Motor Controllers
Class-D Switching Amplifiers
Line Drivers
Pulse Transformer Driver
