L6391：High voltage high and low-side driver
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.
