Si82XX EVALUATION BOARD USER’S GUIDE
1. Introduction
The Si823x isolated driver family combines two independent isolated drivers into a single package. The Si8230/1/
3/4 are high-side/low-side drivers, and the Si8232/5/6 are dual drivers. Versions with peak output currents of 0.5 A
(Si8230/1/2) and 4.0 A (Si8233/4/5/6) are available. The Si8220/21 is a high-performance functional upgrade for
opto-coupled drivers, such as the HCPL-3120 and the HPCL-0302 providing 2.5 A of peak output current. These
ISOdrivers utilize Silicon Laboratories' proprietary silicon isolation technology, which provides a choice of 2.5, 3.75,
or 5.0 kVrms withstand voltages. All drivers operate with a maximum output supply voltage of 24 V. High
integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the family ideal for a
wide range of isolated MOSFET/IGBT gate drive applications.
The Si82xx evaluation board allows designers to evaluate Silicon Lab's family of ISOdrivers. The boards come
populated with 5 kVrms versions of the Si8220, Si8233, Si8234, and Si8235. The board includes land pads for
common surface mount and through-hole packaged FET/IGBT power transistors. The board also includes patch
area for additional prototyping that can be used to accommodate any load configuration a designer might need to
evaluate. For more ISOdriver information, visit Silicon Labs web site at www.silabs.com/isolation. The product data
sheet and numerous application notes can be referenced to help facilitate designs.
