Description

The L6390 is a high-voltage device manufactured with the BCD OFF-LINE technology. It is a monolithic 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 operational amplifier suitable for advanced current sensing in applications such as field oriented motor control.

An integrated comparator is available for protections against over-current, over-temperature, etc.
