SM72482

SolarMagic Dual 5A Compound Gate Driver

Fast rise and fall times (14 ns/12 ns rise/fall with 2 nF load)

■

General Description

Available in dual non-inverting, dual inverting and

combination configurations

Supply rail under-voltage lockout protection (UVLO)

The SM72482 Dual Gate Driver replaces industry standard

gate drivers with improved peak output current and efficiency.

Each “compound” output driver stage includes MOS and bipo-

lar transistors operating in parallel that together sink more

than 5A peak from capacitive loads. Combining the unique

characteristics of MOS and bipolar devices reduces drive cur-

rent variation with voltage and temperature. Under-voltage

lockout protection is also provided. The drivers can be oper-

ated in parallel with inputs and outputs connected to double

the drive current capability. This device is available in the

SOIC-8 package.
