  • The L6391 is a high voltage device manufactured with the BCD™ “OFF-LINE” technology. It is a single-chip half-bridge gate driver for N-channel power MOSFET or IGBT.

    The high-side (floating) section is designed to stand a voltage rail up to 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing the microcontroller/DSP.
    An integrated comparator is available for protections against overcurrent, overtemperature, etc.

    Key Features

    • High voltage rail up to 600 V
    • dV/dt immunity ± 50 V/nsec in full temperature range
    • Driver current capability:
      • 290 mA source
      • 430 mA sink
    • Switching times 75/35 nsec rise/fall with 1 nF load
    • 3.3 V, 5 V TTL/CMOS inputs with hysteresis
    • Integrated bootstrap diode
    • Comparator for fault protections
    • Smart shutdown function
    • Adjustable deadtime
    • Interlocking function
    • Compact and simplified layout
    • Bill of material reduction
    • Effective fault protection
    • Flexible, easy and fast design
