LM5100CMAX [Texas Instruments]

These high-voltage gate drivers are designed to drive both the high-side and the low-side N-Channel MOSFETs in synchronous buck or half-bridge configurations. The floating high-side driver can operate with supply voltages up to 100V. The A versions provide 3-A gate drive, while the B and C versions provide 2-A and 1-A, respectively. The outputs are independently controlled with CMOS input thresholds (LM5100A/B/C) or TTL input thresholds (LM5101A/B/C). Key features include bootstrap supply voltage up to 118V DC, fast propagation times (25-ns typical), excellent propagation delay matching (3-ns typical), undervoltage lockout on both low-side and high-side power rails, and low power consumption. They are pin compatible with HIP2100/HIP2101 and available in multiple packages.
