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.
