 LM5111   
Dual 5A Compound Gate Driver 		Click link to Download

Features

  • 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)
  • Fast rise and fall times (14 ns/12 ns rise/fall with 2 nF load)
  • Available in dual non-inverting, dual inverting and combination configurations
  • Supply rail under-voltage lockout protection (UVLO)
  • LM5111-4 UVLO configured to drive PFET through OUT_A and NFET through OUT_B
  • Pin compatible with industry standard gate drivers

    • Description

    The LM5111 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-8 package or the thermally enhanced MSOP8-EP package.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
