Introduction

3 Introduction

3.1 Evaluation Board Features

This family of devices is designed for low-voltage automotive lighting applications. Its four low RDS(ON) MOSFETs can control:• Four separate 55W / 28W bulbs• Four separate Xenon modules• Four separate LEDs• Four separate Other type of loads

In addition, this family of devices has the following features:• Programming, control, and diagnostics are accomplished using a 16-bit SPI interface.• Its output with selectable slew-rate allows to satisfy electromagnetic compatibility (EMC)

requirements.• Each output can be controlled with an internal PWM modulated clock signal, instead of an external

clock.

3.2 Device Features

• Four protected high-side switches• Operating voltage range of 6.0V to 20V with sleep current < 5.0μA, extended mode from 4.0V to 28V• 8 MHz 16-bit 3.3V and 5V SPI control and status reporting with daisy chain capability• PWM module using external clock or calibratable internal oscillator with programmable outputs delay

management• Smart over-current shutdown, severe short-circuit, over-temperature protections with time limited

auto-retry, and fail-safe mode in case of MCU damage• Output OFF or ON open-load detection compliant to bulbs or LEDs and short-to-battery detection.

Analog current feedback with selectable ratio and board temperature feedback.

3.3 KITUSBSPIEVME USB-to-Parallel Converter Board

The KITUSBSPIEVME board converts from USB to SPI and from USB to parallel data transmission. The main function provided by this board is to allow a PC that may not have a parallel port to communicate with other Freescale Evaluation Boards via a USB port.

.

Required Equipment

4 Required EquipmentMinimum required equipment:• Power DC supply 40A/20V• 5.0 V power supply, 1.0 A current capability• Computer with an available USB port, running Windows XP or higher• KITUSBSPIEVME board for converting from USB to SPI• SPIGen software, which is available from the Freescale SPIGen website (also from the evaluation kit’s

CD-ROM)• Ty

5 Evaluation Board ConfigurationThe typical evaluation board (EVB) shown below utilizes the KITUSBSPIEVME as an alternate communication interface to a PC, instead of a 25 pin parallel I/O connector/cable. These EVBs have been designed to use SPIGen software in order to communicate and control the device functions on the evaluation board. The figure below illustrates a typical EVB and how you would configure it to work with a KITUSBSPIEVME interface board, for a USB connection to a PC.

Evaluation Board Configuration

Verify that the SI signal (Slave Input of the Serial Peripheral Input bus) on the EVB connects to the 25-pin parallel connector on pin 3. If instead it is on pin 6, then the jumper matrix (Figure 4) of the KITUSBSPIEVMEwill have to be configured in the following way:1. Remove the jumper between pins SI and 3.2. Remove the jumper between pins Data1 and 6.3. Connect a jumper between pin SI and pin 6

Installing SPIGen Freeware on your Computer

6 Installing SPIGen Freeware on your ComputerThe latest version of SPIGen can be downloaded from the SPIGen web page at www.freescale.com (see the References section) and is designed to run on any Windows 7, Vista or XP-based operating system. SPIGen is also included on the CD-ROM supplied with the board, though this version may not be as up-to-date as that available from the SPIGen web page.

Before you install the program, refer to the SPIGen README.txt file to check the compatibility of the installation program and your computer operating system. For each operating system, README.txt describes where the software should be installed.

For computers running Windows 7, Vista, or Windows XP, download the SPIGen 7 install program from the SPIGen website. When the download is complete, run the install program. Several temporary files will be copied to your computer, and then the Installation Wizard will guide you through the rest of the process.

To install the software from the CD-ROM, insert the CD-ROM into your CD drive.

To use SPIGen, go to the Windows Start menu, then Programs, then SPIGen, and click on the SPIGen icon. The SPIGen Graphic User Interface (GUI) will appear. Go to the File menu in the upper left hand corner of the GUI, and select Open. In the file selection window that appears, set the “Files of type: ” drop-down menu to “All Files (*.*)”. Next, browse the CD-ROM from the evaluation board kit and select the file called “SPIGen Config File.txt”. Click Open, and SPIGen will open a specifically configured SPI command generator for your EVB.

The GUI is shown in Figure 5. The text at the top is the name of the configuration file loaded. (As an exceptional case, the file name has a .txt extension for the boards covered by this user’s guide. In other cases, the standard .spi extension will be evident.) The left side panel displays folders that group user interfaces. The boards associated with this guide will all make use of the Generic user interfaces. (The other pre-installed folders contain interfaces for boards unrelated to this document.) The process of loading the configuration files has assigned a list of “Extra Pins” as well as a list “Quick Commands”, all of which are specific to the board in use.

Figure 5. SPIGen GUI


Setup and Using the Hardware

7 Setup and Using the HardwareWarning: Always wear safety glasses when working around electronic modules and when soldering.

Please remove the capacitor C4 when testing reverse supply on Vpwr.1. The EVB allows the customer to quickly evaluate features of the device with a simple bench top setup.

All switch inputs may be evaluated using the onboard switch banks or actual system switches connected to the switch input edge connector.

2. Using a standard 25 pin Sub-D parallel port cable and the enclosed SPIGen SPI software, you can use a personal computer to provide the Serial Peripheral Interface (SPI) communication with this EVB (see SETUP_EVB).

3. Connect power supply to the VPWR and GND terminals on the EVB. Make sure the voltages provided are in accordance with the device data sheet and that the supply currents are sufficient to supply the switch contact wetting current. A voltage of +5V is needed for SPI communication. This voltage can be provided from PC via parallel cable (JP9 must be inserted) or through an external power supply via connector VDD. Without +5V the device will be in fail-safe mode.

4. Connect desired external load between one of the output (OUT0 - OUT3) and power supply ground. 5. For direct control of the outputs apply +5V on connectors IN0 - IN3. Corresponding HS output turns-on. Each IN

input wakes the device.6. For preparing the evaluation board for SPIGen, place jumpers JP9, JP10 to 1-2 position.7. For instructions on installing the SPIGen software and loading the configuration file, see ”Installing SPIGen

Freeware on your Computer”. The configuration file will set all parameters for SPI signals from the PC and provide a list of commands that may be sent to the EVB.

8. To set up the device to read switch inputs the user may use the batch commands from the Batch Commands view. To send a batch of commands to the EVB, select the batch command from the “Batch Name” drop-down box and click the Send Once button. To quickly evaluate the EVB and device, simply click on the Single Command view, select the switch status command from the Quick Commands list and click the Send Continuous button. The opening and closing of switches may now be seen on the Word Received bits window field. Refer to the device data sheet for detailed information on I/O communication and device operation.
