ISL54302EVAL1Z Evaluation Board

User’s Manual

Application Note March 18, 2008

Before Getting Started

Voltage Supplies

This document supplements the ISL54302 data sheet FN6592. Evaluation board users should review that document to obtain information on the part’s basic functionality and power requirements. Important Note:

before powering up the board, review the Power-Up Sequence section in the ISL54302 data sheet. There are

many DC sources utilized, so a user may inadvertently misapply the power sources causing damage to the part.

Take time to review the ISL54302 Data Sheet (FN6592) and become familiar with the part’s basic functions and power options. Note also that FN6591 supersedes this document with respect to updates and modifications. Always refer to that document if discrepancies occur .

No signal should be more positive than VPLUS or more negative than VSS. Also, all voltages are reference to the GND Pin. Under all circumstances, VLOGIC should be 3.0V ±10% and VDD should also be 3.0V above VSS.

AN1382.0

Two buttons are located on the right hand side of the user screen. They provide a quick means of testing the computer to Dongle communications. Clicking on the “Led’s On” will turn on the Green and Red Led’s located on the USB Dongle. Clicking “Led’s Off” will turn them off again.

If the LED’s fail to respond:

1. Exit the application and restart the application.

2. Exit the application, disconnect the USB cable, wait for the USB disconnect tone, then connect the USB, wait for the connect tone and restart the application.

Once you can successfully turn the Dongle Led’s on and off, you are ready to start working with ISL54302 device.

Software Installation

This ISL54302EVAL1Z Evaluation board comes with software for operating the switch conditions of the board. This feature is based in a USB interface dongle that Intersil uses in many applications. This dongle comes pretested and plugged into the ISL54302EVAL1Z Evaluation board. Care should be taken not to inadvertently remove the dongle from the evaluation board as it is detachable. It is detachable so the user can remove the Dongle and connect a customer specific control if desired.

Before attaching the USB cable or applying power to the Evaluation board banana jacks, the user must execute the installation program.

Intersil_ISL54302_Installer .Exe. This program not only installs the Evaluation Software, but also installs the USB drivers needed to communicate with the Intersil USB Dongle.

Double click on the installer program to execute and follow the defaults for performing the installation.

All Intersil Evaluation Software is placed in a directory in the Windows “Program Files” Directory. After installation the software is available at: All Programs/Intersil/Intersil_54302. In that directory will be both the execution program and the uninstaller.

Device Power Supply Banana Jacks

There are five banana jacks located on the edge of the board.

• GND - the reference for all supplies always 0Vs

• VSS - the negative switch operating range (-3V to 0V)

• VDD - digital logic supply, always VSS + 3V

• VLOGIC - digital interface reference always 3V

• VPLUS - Positive switch operation range, 5V to 9V

Apply these voltages in the order detailed in the device specification.

Test Setup Voltages

The user may wish to adopt the procedure outlined in the “Initial Power-Up” section on page 2.

Once installation is complete, connect the USB cable. You will receive audio notice that the new device is ready for use. Once this occurs, double click on the ISL54302 application. The operator interface screen will appear on your desktop.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Scope Probe Connections

Another topic to cover before getting started is the evaluation board physical connections for waveform observations. On each schematic version, you will see a component with pins designated as leadless scope probe connections. This is not an active component but a dual pin header physically designed to accommodate connection of Active/ Differential Probes. This will minimize Ground Lead Inductance and Capacitive Loading while make waveform observations. However, the user must also be mindful of Max Voltage Limitations when using these types of probes.

= LEADLESS SCOPE PROBE CONNECTION

BNC (Switch Contact) Connections

The evaluation board provides BNC connections for Switch Contact A and Switch Contact B signals see Figures 2 and 3. Since the ISL54302 is a quad switch device, there are eight BNC connections to the evaluation board.

Initial Power-Up

Please refer to the device specifications found in the FN6592 data sheet for power-up sequencing and current requirements.

Test Setup Voltages

To get started, the user may wish to adopt the following voltages which provide an analog switch range that is rail-to-rail. With these conditions, the user needs only three power supplies to get started.

• VSS = GND = 0V

• VDD = VLOGIC = 3V

• VPLUS = +6V to + 12V The user can now open and close each switch via the

software by checking and unchecking the switch controls and click the “Write” button.

Test Procedure

First Time Setup

SOFTWARE INSTALLATION AND BASIC COMMUNICATIONS CHECK

1. Remove the USB cable; do not have Evaluation board USB cable connected during software installation

2. Double click the provided installation file and follow the instructions for installation

- Intersil_ISL54302_Installer.Exe.

3. When finished, exit the installation software.

4. Connect the USB cable between the Evaluation board and your computer.

5. Run the Evaluation software. Start\ All Programs\Intersil\ ISL54302 Demo

Test Procedure Fo r Each Board Under Test.

1. Connect USB cable between your computer and the evaluation board.

2. Start the Evaluation Software

- “Start\All Programs\Intersil\ISL54302 Demo”

3. Verify the LED’s turn on and of f. (Click Led’s On/Led’s Of f buttons on user screen.)

4. Apply power to the Evaluation Banana Jack,as specified in the FN6592 (ISL54302 Data Sheet)

5. Verify approximate currents (Electrical Specifications Table)

6. Place an ohm meter across each set of switch contacts and open and close each switch with the software. Click the associated switch check box and click “Write” button. When the switch is closed, the resistance should be less than 5Ω, and when open, it should be greater than 500k.

7. If all switches operate, board test is successful.

Schematic Information

This evaluation board supports the ISL54301 and ISL54302. In the case of the ISL54302, the Cheetah Connection is not used. This also explains why there are scope probe test points and connections made to pins designated as NC - “No Connection” on the ISL54302 version of the Evaluation board see Figure 4.
