L6491:High voltage high and low-side 4 A gate driver

The L6491 is a high voltage device manufactured with the BCD6 “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 microcontroller/DSP.

An integrated comparator is available for fast protection against overcurrent, overtemperature, etc.
