Features
  • Drives both a high side and low side N-channel MOSFET
  • Independently programmable high and low side rising edge delay
  • Bootstrap supply voltage range up to 118V DC
  • Fast turn-off propagation delay (25 ns typical)
  • Drives 1000 pF loads with 15 ns rise and fall times
  • Supply rail under-voltage lockout
  • Low power consumption
  • Timer can be terminated midway through sequence
  • Description

    The LM5102 High Voltage Gate Driver is 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 supply voltages up to 100V. The outputs are independently controlled. The rising edge of each output can be independently delayed with a programming resistor. An integrated high voltage diode is provided to charge the high side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing clean level transitions from control logic to the high side gate driver. Under-voltage lockout is provided on both the low side and the high side power rails. This device is available in the standard MSOP-10 pin and the LLP-10 pin 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.
