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 bipolar 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 current variation with voltage and temperature.

Under-voltage lockout protection is also provided.

The drivers can be operated in parallel with inputs

and outputs connected to double the drive current

capability. This device is available in the SOIC

package.
