EVAL6494L

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 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.  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 DocID031198 Rev 1 For further information contact your local STMicroelectronics sales office. 1/7 www.st.com 2/7 */ 4% 716 7$$ (/%             7QV 7DD 18. 4% 7QV 7DD 18. 4% DocID031198 Rev 1 53  %5 3 $ $ */ +1 01&/ 7DD7QV Q'7 +1 %5 18. 7DD $ 7DD 7QV 51 3 3 /.
