Si826X LED EMULATOR INPUT ISODRIVER
EVALUATION BOARD USER’S 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 drivers utilize Silicon Laboratories'
proprietary silicon isolation
technology, supporting up to 5.0 kV
RMS 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 circuit mimics the characteristics of an LED, less drive
current is required, resulting in higher efficiency. Propagation 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 consists of four separately orderable boards with each board
featuring either the DIP8, SOIC8, SDIP6, or LGA8 package. For more information on configuring the ISOdriver
itself, see the Si826x product data sheet and application note “AN677: Using the Si826x Family of Isolated Gate
Drivers”.
