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.
