FEATURES
DESCRIPTION
The LM5111 Dual Gate Driver replaces industry
2
• Independently Drives Two N-Channel
standard gate drivers with improved peak output
MOSFETs
current and efficiency. Each “compound” output driver
• Compound CMOS and Bipolar Outputs Reduce
stage includes MOS and bipolar transistors operating
Output Current Variation
in parallel that together sink more than 5A peak from
capacitive loads. Combining the unique
• 5A Sink/3A Source Current Capability
characteristics of MOS and bipolar devices reduces
• Two Channels can be Connected in Parallel to
drive current variation with voltage and temperature.
Double the Drive Current
Under-voltage lockout protection is also provided.
• Independent Inputs (TTL Compatible)
The drivers can be operated in parallel with inputs
and outputs connected to double the drive current
