UG367: Si823Hx/8252x-EVB User's Guide
The Si823Hx/8252x isolated gate drivers are ideal for driving power switches used
in a wide variety of power supplies, inverters, and motor control applications offering
longer service life and dramatically higher reliability compared to opto-coupled gate
drivers. The Si823Hx/8252x isolated gate drivers utilize Skyworks' proprietary silicon
isolation technology that supports up to 5 kVRMS withstand voltage per UL1577. This
technology enables industry-leading, common-mode transient immunity (CMTI), tight
timing specifications, reduced variation with temperature and age, better part-to-part
matching, and extremely high reliability. It also offers unique features, such as separate
pull-up/down outputs, driver shutdown on UVLO fault, and precise dead time programm-
ability. Driver outputs can be grounded to the same or separate grounds or connected
to a positive or negative voltage. TTL level compatible inputs with 800 mV hysteresis
are available in individual control input (Si823H1/2/3/5/6/7 and Si82520) or PWM input
(Si823H4/8) configurations. High integration, low propagation delay, small installed size,
flexibility, and cost-effectiveness make this family ideal for a wide range of isolated
MOSFET/IGBT/SiC/GaN gate drive applications.
The Si823Hx/8252x evaluation board allows designers to evaluate Skyworks' Si823Hx/
8252x family of high CMTI performance ISOdrivers. The board includes screw terminals
for quick evaluation of key device parameters and includes test points on each device's
pins to accommodate direct connection to the designer's end system. For more ISOdriv-
er information, visit the Skyworks web site at www.skyworksinc.com//products/isolation.
The product data sheet and numerous application notes can be referenced to help
facilitate designs.
