Description

The L6498 is a high voltage device manufactured

with the BCD6 “OFF-LINE” 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 DC voltage rail up to 500 V, with 600 V

transient withstand voltage. The logic inputs are

CMOS/TTL compatible down to 3.3 V for easy

interfacing control units such as microcontrollers

or DSP.

Both device outputs can sink 2.5 A and source 2

A, making the L6498 particularly suited for

medium and high capacity power

MOSFETsIGBTs.

The outputs cannot be simultaneously driven high

thanks to an integrated interlocking function.

The independent UVLO protection circuits

present on both the lower and upper driving

sections prevent the power switches from being

operated in low efficiency or dangerous

conditions.

The integrated bootstrap diode as well as all of

the integrated features of this driver make the

application PCB design simpler and more

compact, and help to reduce the overall bill of

material.
