UG186: Si827x-EVB User's Guide
The Si827x isolated gate drivers are ideal for driving power switches used in a wide vari-
ety 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 Silicon Laboratories' proprietary silicon isolation technology
supporting up to 2.5 kV
RMS
withstand voltage per UL1577 and VDE0884. This technolo-
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 in-
tegration, 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 Silicon Lab's Si827x family of
high CMTI performance ISOdrivers. The boards come populated with the Si8271 and ei-
ther the Si8273, Si8274, or Si8275 version of the family. The board includes screw ter-
minals 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.
