UG367: Si823Hx-EVB User's Guide
The Si823Hx isolated gate drivers are ideal for driving power switches used in a wide
variety of power supply, inverter, and motor control applications, offering longer serv-
ice life and dramatically higher reliability compared to opto-coupled gate drivers. The
Si823Hx 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. The 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 the family ideal for a wide range of
isolated MOSFET/IGBT/SiC/GaN gate drive applications.
The Si823Hx evaluation board allows designers to evaluate Skyworks' Si823Hx family
of high CMTI performance ISOdrivers. The boards come populated with either the
Si823H2, Si82520, or two Si823H9 version of the family. The board includes screw
terminals for quick evaluation of the devices’ key parameters and includes test points on
each devices’ pins to accommodate direct connection to the designer’s end system. For

enced to help facilitate designs.
