Si82Xx Isodriver Board Overview - Silicon Laboratories Si82 Series User Manual

3. Si82xx ISOdriver Board Overview

The Si82xx evaluation board is populated with the following ISOdrivers:
Si8220 in wide-body SOIC-16 package, opto-input, 2.5 A, 5 kV ISOdriver

Si8233 in wide-body SOIC-16 package, 2-input, 4 A, 5 kV High-Side/Low-Side ISOdriver

Si8234 in wide-body SOIC-16 package, PWM-input, 4 A, 5 kV High-Side/Low-Side ISOdriver

Si8235 in wide-body SOIC-16 package, 2-input, 4 A, 5 kV Dual ISOdriver

High-side and low-side land pads for surface mount packaged FET/IGBT power transistors (not populated)

High-side and low-side land pads for through-hole packaged FET/IGBT power transistors (not populated)

Patch area

The Si82xx board is four separate evaluation boards in one, with each section featuring a different ISOdriver
(Si8220, Si8233, Si8234, or Si8235). Each section is isolated from the other sections and requires its own power
supplies to power the given section's ISOdriver. Each section's ISOdriver is designed to be powered separately
with input supplies for VDDI (5.5 V, 500 mA) and output supplies for VDDA, VDDB, or VDD up to 24 V. The user is
expected to connect their desired drive-trane topology and load to the outputs of the appropriate ISOdriver and the
patch area. Figure 2 shows a silkscreen overview of the board.
Please note the voltage rating for the prepopulated components in the Si82xx BOM section of this document before
applying power to the ISOdriver and customer specific driver-trane. Applying a voltage to a component that is
higher than its rating can cause permanent device damage. If the install components do not meet the user's
requirements, these components need to be replaced before proceeding. Moreover, if a user wants to evaluate an
ISOdriver in a wide-body package other than the ones populated, this can be accomplished by removing the
footprint-compatible device installed on the evaluation board and replacing it with the desired footprint-compatible
ISOdriver.
