UG390: Si834x-EVB User Guide
Description
The Si834x-IF provides up to four isolated high-side
(sourcing) or low-side (sinking) switches with low RON.
These switches are ideal for driving resistive and induc-
tive loads such as solenoids, relays, and lamps com-
monly found in industrial control systems like PLCs.
Each switch is galvanically isolated for safety using Sky-
works Solutions’ ground-breaking CMOS-based isola-
tion technology which enables easy interfacing with
low voltage 2.25 V MCUs and high CMTI (100 kV/µs).
The Si834x evaluation board allows designers to evalu-
ate Skyworks’ Si834x family of Isolated Smart
Switches. Each board comes populated with one
Si834x device, LED status indicators, pluggable load
terminals for evaluation of the device's key parame-
ters, and test points for monitoring device pins. Addi-
tional information on the Si834x products can be
found at https://www.skyworksinc.com/Products/Iso-
lation. The product data sheet and application notes
can be referenced to help facilitate designs.

2. Test Procedure
The procedure below assumes you are familiar with the Si834x device. If not, see “3. Using the Evaluation Board”
on page 7 for key background information. Throughout this document, “sourcing” (or SRC) refers to Si8340x part
numbers and their corresponding sourcing PCBs, and “sinking” (or SNK) refers to Si8341x part numbers and their
corresponding sinking EVBs.
The following equipment is required to demonstrate the evaluation board features:
• Function generator
• One dual-channel dc power supply or two single supplies: 0–5 V and 0–24 V
• One oscilloscope with at least two channels
• Up to four kΩthrough-hole resistors (1 minimum)
• Si834x-EVB kit
- Si834x-EVB User’s Guide (this document)
• Assorted cables, leads, and probes as necessary to connect equipment to EVB
2.1. DC Supply Configuration
2.1.1. VDD1 Supply Configuration
1. Set one supply to output 5 VDC.
2. Turn OFF the supply and connect the positive lead to VDD1 (J3-1 or TP18).
3. Connect the negative lead to GND1 (J3-2 or TP20).
4. Turn ON the supply.
5. Ensure that LED D7 turns on and that LED D5 is blinking (this indicates there is no VDD2 supply).
6. Ensure that the current draw is less than 25 mA. If it is larger, this indicates that either the board or Si834x
has been damaged or that the supply is connected backwards.
2.1.2. VDD2 Supply Configuration
1. Set the second supply to output 0 VDC.
2. Turn OFF the supply and connect the positive lead to VDD2 (J4-1 or TP19).
3. Connect the negative lead to GND2 (J4-2 or TP21).
4. Turn ON the supply.
5. Slowly ramp the voltage from 0 VDC to 24 VDC.
6. Ensure that LED D8 turns on and that LED D5 turns off.
7. Ensure that the current draw is less than 25 mA. If it is larger, this indicates that either the board or the
Si834x has been damaged or that the supply is connected backwards.

2.2. Input Configuration Procedure
1. Turn ON the function generator with the output disabled. If you do not have a waveform generator, or pre-
fer not to use one, you may simply apply 5 V to the input channels on the Si834x to observe the output
channel coming on. The proper configuration is shown in the figures below.
2. Adjust the output to provide a 100 Hz, 0 to 5 V peak square wave with 50% duty cycle.
3. Connect the positive lead of the generator to A1 (J1-1 or TP1) and ground the connection to GND1 (J1, J3,
or TP20).
4. If possible, configure the function generator for a High-Z (high-impedance) load.

2.3. Load Configuration
1. Turn OFF the 24 VDC power supply.
2. Connect a 10 kΩresistor to channel B1 by placing one lead in the first slot of the terminal block (J2) and
screwing it down. Place the other lead in the second slot (J2) and screw it down. This connection is the
same for both SRC and SNK EVBs.
3. Populate all remaining channels (B2, B3, and B4 if possible) with the remaining resistors.
4. Turn ON the 24 V supply.
2.4. Oscilloscope Setup
1. Connect the CH1 probe to A1 (TP1) and ground the probe to GND1 (TP20).
2. Connect the CH2 probe to B1 (TP6) and ground the probe to GND2 (TP21).
3. Set the scope to Trigger on a rising edge on CH1 and adjust the trigger level to approximately 2 V.
4. Set CH1 to 2 V per division and CH2 to 10 V per division.
5. Adjust the horizontal zoom to 500 µs per division.

2.5. Activate Channels
1. Enable the function generator output on Channel A1 or apply 5 V directly.
2. Ensure that D1 turns on.
3. Adjust the vertical and horizontal divisions to properly view the waveform as seen in the image below.
A 100 Hz square wave with 50% duty cycle should appear on Channel 1, and a similar waveform with peak voltage
of 24 V should appear on Channel 2. Note that the output waveform in the figure below is for a sourcing device,
and the polarity will be opposite for sinking devices.
Figure 4. Oscilloscope Waveform with 100 Hz Square Wave Input
2.6. Repeat for Remaining Channels (if Applicable)
1. Disable the function generator output.
2. Connect the CH1 probe to A2 (TP2).
3. Connect the CH2 probe to B2 (TP7).
4. Connect the positive lead of the function generator to A2 (TP2).
5. Enable the function generator.
6. Ensure that LED D2 turns on.
7. For Si834x4AAA EVBs, repeat steps 1–5 with channels A3 and A4 using test point TP3 for A3, TP5 for B3, TP4
for A4, and TP8 for B4.

3. Using the Evaluation Board
The Si834x-EVB comes populated with one of six different Si834x devices that may require different input types
and load configurations. This section explains those differences as well as how to configure your setup to properly
utilize the evaluation board.
3.1. Load Termination
Sourcing parts utilize high side switches that require the load to be connected from the channel output (Bn) to
GND2. Sinking parts contain a low side switch that require the load to instead be connected from output (Bn) to
VDD2. The output-side screw terminals (J2) on the sourcing EVBs contain connections to GND2, while the sinking
EVBs contain connections to VDD2. This allows J2 Pins 2, 4, 6, and 8 to be used for load termination on both the
sourcing and sinking evaluation boards.
