Description
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 microcontroller/DSP.
An integrated comparator is available for
protections against overcurrent, overtemperature,
etc.
