SolarMagic Dual 5A Compound Gate Driver

General Description

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.
