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.
Features
Renewable Energy Grade
Independently drives two N-Channel MOSFETs
Compound CMOS and bipolar outputs reduce output
current variation
5A sink/3A source current capability
Two channels can be connected in parallel to double the
drive current
Independent inputs (TTL compatible)
Fast propagation times (25 ns typical)
