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.Key Features
- High voltage rail up to 600 V
