  • Independent TTL compatible inputs
  • Integrated bootstrap diode
  • Bootstrap supply voltage to 118V DC
  • Fast propagation times (27 ns typical)
  • Drives 1000 pF load with 15ns rise and fall times
  • Excellent propagation delay matching (2 ns typical)
  • Supply rail under-voltage lockout
  • Low power consumption
  • Pin compatible with ISL6700
  • Description

    The LM5107 is a low cost high voltage gate driver, designed to drive both the high side and the low side N-Channel MOSFETs in a synchronous buck or a half bridge configuration. The floating high-side driver is capable of working with rail voltages up to 100V. The outputs are independently controlled with TTL compatible input thresholds. An integrated on chip high voltage diode is provided to charge the high side gate drive bootstrap capacitor. A robust level shifter technology operates at high speed while consuming low power and providing clean level transitions from the control input logic to the high side gate driver. Under-voltage lockout is provided on both the low side and the high side power rails. The device is available in the SOIC-8 and the thermally enhanced LLP-8 packages.

    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.
