L6494L Gate Driver Demonstration Board

EVAL6494L

Overview

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 MOSFETsIGBTs.
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.
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.
