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 Solutions' proprietary silicon
isolation technology supporting up to 5 kVRMS withstand voltage per UL1577 and
VDE0884. 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 programmability. 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 boards come populated with
either the Si823H2, Si82520, or two Si823H9 versions of the family. The board in-
cludes 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 ISOdriver information, visit the Skyworks web site at

can be referenced to help facilitate designs.
