UG367: Si823Hx-EVB User's Guide

PublishTime：2020-04-16

The Si823Hx isolated gate drivers are ideal for driving power switches used in a widevariety of power supply, inverter, and motor control applications, offering longer servicelife and dramatically higher reliability compared to opto-coupled gate drivers. TheSi823Hx isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolationtechnology 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 sep-arate pull-up/down outputs, driver shutdown on UVLO fault, and precise dead time pro-grammability. Driver outputs can be grounded to the same or separate grounds or con-nected to a positive or negative voltage. The TTL level compatible inputs with 800 mVhysteresis are available in individual control input (Si823H1/2/3/5/6/7 and Si82520) orPWM input (Si823H4/8) configurations. High integration, low propagation delay, small in-stalled size, flexibility, and cost-effectiveness make the family ideal for a wide range ofisolated MOSFET/IGBT/SiC/GaN gate drive applications.The Si823Hx evaluation board allows designers to evaluate Silicon Lab's Si823Hx familyof high CMTI performance ISOdrivers. The boards come populated with either theSi823H2, Si82520, or two Si823H9 version of the family. The board includes screw ter-minals for quick evaluation of the devices’ key parameters and includes test points oneach devices’ pins to accommodate direct connection to the designer’s end system.
