Skyworks Si8271 User Manual

UG186: Si827x-EVB User's Guide
The Si827x isolated gate drivers are ideal for driving power switches used in a wide
variety of power supply, inverter, and motor control applications, offering longer service
life and dramatically higher reliability compared to opto-coupled gate drivers. The Si827x
isolated gate drivers utilize Skyworks Solutions' proprietary silicon isolation technology
supporting up to 2.5 kV
RMS
gy enables industry-leading common-mode transient immunity (CMTI), tight timing spec-
ifications, 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 >400 mV hysteresis are available
in individual control input (Si8271/2/3/5) or PWM input (Si8274) 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 Si827x evaluation board allows designers to evaluate Skyworks' Si827x family of
high CMTI performance ISOdrivers. The boards come populated with the Si8271 and
either the Si8273, Si8274, or Si8275 version of the family. The board includes screw
terminals for quick evaluation of the devices' key parameters and also includes test
points on each devices' pins to accommodate direct connection to the designer's end
system. For more ISOdriver information, visit Skyworks web site at
sinc.com/Products/Isolation. The product data sheet and numerous application notes
can be referenced to help facilitate designs.
