FEATURES
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

•
Renewable Energy Grade
Independently Drives Two N-Channel
MOSFETs
•
Compound CMOS and Bipolar Outputs Reduce
Output Current Variation
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.

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)
Fast Rise and Fall Times (14 ns Rise, 12 ns
Fall With 2 nF Load)
