EVAL6494L
Demonstration board for L6494L gate driver
Data brief
Description
The L6494L 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 MOSFETs or IGBTs.
Both device outputs can sink 2.5 A and source 2
A, making the L6494L particularly suited for
medium and high capacity power
MOSFETs\IGBTs.
The integrated bootstrap diode as well as all of
the integrated features of this driver make the
application's PCB design simpler and more
compact, and help reducing the overall bill of
material.
Features
Driver current capability: 2 A source, 2.5 A sink
Integrated bootstrap diode
Single input and shutdown pin
Adjustable deadtime
3.3 V, 5 V TTL/CMOS inputs with hysteresis
UVLO on both high-side and low-side sections
dV/dt immunity: 50 V/ns in full temperature
range
Compact and simplified layout
Bill of material reduction
Flexible, easy and fast design
The EVAL6494L board allows evaluating all of the
L6494L features while driving a power switch in
the TO-220 or TO-247 package.
The board allows easily to select and modify the
values of relevant external components in order to
ease driver performance evaluation under
different applicative conditions and fine pre-tuning
of final application components.
