Description

The L6491 is a high voltage device manufactured

with the BCD6 “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.

An integrated comparator is available for fast

protection against overcurrent, overtemperature,

etc.
