L6393   Product is in volume production.

Half bridge gate driver

Download Datasheet

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.
