Features • Drives both a high-side and low-side N-Channel MOSFETs • Independent high and low driver logic inputs • Bootstrap supply voltage up to 118V DC • Fast propagation times (25 ns typical) • Drives 1000 pF load with 8 ns rise and fall times • Excellent propagation delay matching (3 ns typical) • Supply rail under-voltage lockout • Low power consumption • Pin compatible with HIP2100/HIP2101 Description The LM5100A/B/C and LM5101A/B/C High Voltage Gate Drivers are 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 operating with supply voltages up to 100V. The “A” versions provide a full 3A of gate drive while the “B” and “C” versions provide 2A and 1A respectively. The outputs are independently controlled with CMOS input thresholds (LM5100A/B/C) or TTL input thresholds (LM5101A/B/C). 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 the control logic to the high-side gate driver. Under-voltage lockout is provided on both the low-side and the high-side power rails. These devices are available in the standard SOIC-8 pin, PSOP-8 pin and the LLP-10 pin packages. The LM5100C and LM5101C are also available in eMSOP-8 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.
