Half-bridge gate driver
Description
The L6393 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.
The IC embeds an uncommitted comparator
available for protections against overcurrent,
overtemperature, etc.
