Si826x-EVB Si826X LED EMULATOR INPUT ISODRIVER EVALUATION BOARD USERS GUIDE 1. Introduction The Si826x evaluation board allows designers to evaluate Silicon Lab s Si826x family of CMOS based LED Emulator Input ISOdrivers. The Si826x ISOdrivers are pin-compatible, drop-in upgrades for popular opto-coupled gate drivers, such as 0.6 A ACPL-0302/3020, 2.5 A HCPL-3120/ACPL-3130, HCNW3120/3130, and similar opto- drivers. The devices are ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si826x isolated gate driversutilize Silicon Laboratories proprietary silicon isolation technology, supporting up to 5.0 kVRMS withstand voltage per UL1577. This technology enables higher-performance, reduced variation with temperature and age, tighter part-to-part matching, and superior common-mode rejection compared to opto-coupled gate drivers. While the input rccuit i mimics the characteristics of an LED, less drive current is required, resulting in higher efficiency. Propation ag delay time is independent of input drive current, resulting in consistently short propagation times, tighter unit-to-unit variation, and greater input circuit design flexibility. As a result, the Si826x series offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers. The evaluation kit consistofs four separately orderable boards with each board featuring either the DIP8, SOIC8, SDIP6, or LGA8 package.
