EVAL6498L

EVAL6498L Evaluation board for the L6498L gate driver Data brief Description The L6498L is a high voltage device developed 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 L6498 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 PCB design simpler and more compact, and help to reduce the overall bill of material. Features          Driver current capability: 2 A source, 2.5 A sink Integrated bootstrap diode Interlocking function 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 November 2017 The EVAL6498L board allows all the L6498L features to be evaluated while a power switch in TO-220 or TO-247 package is driven. The board allows the values of relevant external components to be selected and modified so to ease the driver performance evaluation under different applicative conditions and fine pretuning of final application components.
