Description

The L6393 is a high voltage device manufactured

with the BCD™ “offline” technology. It is a single

chip half bridge gate driver for the 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 the easy interfacing

microcontroller/DSP.

The IC embeds an uncommitted comparator

available for protections against overcurrent,

overtemperature, etc.
