Introduction

4 Introduction

This evaluation board demonstrates the capability of the latest eXtreme Switch Gen4 family. This family offers

new combinations of output channels as well as a selection of Rdson values. All devices are

footprint-compatible; therefore, they can all be evaluated using this evaluation board.

This evaluation board can be used to evaluate either the MC07XS6517 or the MC17XS6500 which are both

12 V penta high side devices that feature integrated control with high flexibility, and high number of protection

and diagnostic functions. These devices are designed for low-voltage automotive lighting applications and can

drive a wide range of sources, including HIB ballasts and LEDs.

Programming, control and diagnostics are accomplished using a 16-bit SPI interface, which makes possible a

large array of configurations, diagnostics and protection features. For example, see below:

• Configuration: Output slew rates, PWM frequency with prescaler, output phasing, current sense precision,

etc.

• Protection and diagnostics: under/overvoltage, thermal warning, overcurrent, open load, SPI fail, etc.

These devices also provide analog feedback of the IC's temperature, battery voltage or selectable-channel

current sensing with high precision.

The five channels can be controlled individually by external clock signal or in fail safe mode by using direct inputs

(available for OUT1 through OUT4). This fail-safe mode operation happens whenever communication with the

external microcontroller is lost (due to watchdog time-out) and all protection as well as control remains

operational.

5 Evaluation Board Features

This evaluation board consists of either an MC07XS6517 or MC17XS6500 IC in SOIC 54 or 32 pins with

exposed pads.

This board can control

• Five separate 28 W bulbs

• Three separate 55 W HID ballasts

• Five separate LED modules

• Five separate loads of other types

Device can be driven by the 16-bit SPI using KITUSBSPI with SPIGen software or with direct input signals in

Fail safe mode operation. It also offers the possibility to apply an external clock in order to drive outputs in PWM

operation.

6 MC07XS6517 and MC17XS6500 Device Features

MC07XS6517 and MC17XS6500 are smart + power ICs intended for lighting application. The devices supports

the following functions:

• Five protected high side switches

–3*7mOhms + 2*17 mOhms for the MC07XS6517

–5*17mOhms for the MC17XS6500

• Operating voltage range from 6.0 V to 18 V with sleep current < 5.0 µA.

• 16-bit 5.0 V SPI control, programming and status reporting with daisy chain capability

• PWM module using external clock with programmable slew rates (to satisfy EMC requirements), 8-bit

flexibility for duty cycle and output delay management.

• Smart overcurrent shutdown, severe short circuit detection, overtemperature protections, output short to

battery, undervoltage or overvoltage reporting, etc.

• Open load detection in On or Off state, available for bulbs and LEDs

• Analog temperature and voltage feedback, so current with selectable ratio is optimized for LEDs modules

Accessory Interface Board

KTXSWITCH4UG User’s Guide Rev. 1.0 11/2013

Freescale Semiconductor, Inc. 5

Freescale analog ICs are manufactured using the SMARTMOS process, a combinational BiCMOS

manufacturing flow that integrates precision analog, power functions and dense CMOS logic together on a

single cost-effective die. All power channels are integrated using LFet45V technology.

7 Accessory Interface Board

The eXtreme Switch Gen4 Evaluation board may be used with the KITUSBSPIDGLEVME interface dongle

(shown below), which provides a USB-to-SPI interface. This small board makes use of the USB and SPI ports

built into Freescale’s MC68HC908JW32 microcontroller. The main function provided by this dongle is to allow

Freescale evaluation boards that have an SPI port to communicate with a PC through its USB port.

8 Required Equipment

Minimum equipment required:

• Minimum equipment required for optimal use:

• DC Power supply 30 V/40 A

10 Installing SPIGen Freeware on your Computer

The latest version of SPIGen is designed to run on any Windows 8, Windows 7, Vista or XP-based operating

system. To install the software, go to www.freescale.com/analogtools and select your kit. Click on that link to

open the corresponding Tool Summary Page. Look for “Jump Start Your Design”. Download to your computer

desktop the SPIGen software as well as the associated configuration file.

Run the install program from the desktop. The Installation Wizard will guide you through the rest of the process.

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

“SPIGen Files (*.spi)”. (As an exceptional case, the file name may have a .txt extension, in which case you

should set the menu to “All Files (*.*)”.) Next, browse for the configuration file you saved on your desktop earlier

and select it. Click “Open”, and SPIGen will create a specially configured SPI command generator for your

evaluation board.

The GUI is shown in Figure 4. The text at the top is the name of the configuration file loaded. The left side panel

displays folders that group user interfaces. The process of loading the configuration file has assigned a list of

“Extra Pins” as well as a list “Quick Commands”, all of which are board-specific.

Setting Up and Using the Hardware

11 Setting Up and Using the Hardware

In order to perform the demonstration examples, first set up the evaluation board hardware and software as

follows:

1. Ready the computer and install the latest available version of SPIGen GUI. Then connect the cable

between this interface board and computer. Finally, plug this interface board into the eXtreme Switch Gen4

Evaluation Board.

2. Attach a DC power supply (without turning on the power) to evaluation board’s Vpwr-Gnd connectors and

attach loads to the KIT07XS6517EVBE board. Plug the USB/SPI interface dongle (KITUSBSPIDGLEVME)

directly into the evaluation board.

3. Use as many output terminals as desired.

4. Launch SPIGen and load the GEN4_SPIgen_eval_rev1.spi configuration file obtained from the Jump Start

download.

5. Turn on the power supply with the correct voltage and verify that EVB is supplied correctly by observing the

D6 LEDs with JP1 and JP11 closed. J1 and J7 have to be set either to the Vcc or the µC position. Set all

the LED jumpers, JP2 to JP6, to outputs pins; set the "Extra Pin" RST_B (if J1 in uC position) to high on

the SPIGen GUI and then do the following verification:

6. Click on the "Extra Pins" button INx. The corresponding OUTx LED should turn on.

7. Click on the "Send Once" button. The 'SPI Word Received' at the top of the screen should answer

something different from 0x0000.

Once the steps above are all accomplished, then you are ready to proceed with the remaining examples.

11.1 SPIGen Software information

On the left side of the "device view", you have two options:

• "Single Command": The screen displays 16 bits from the SP interface, so the user can configure them easily

in binary or hexadecimal. You will also find at the top, the corresponding status of SI and SO bits and on

bottom left, the "SPI Word Session Log". Extra pins are also available for configuration.

• "Batch Commands" allows the user to create a specific function using commands that already exist.

Note:

• Some commands and batches of commands are already set up in the GEN4_SPIgen_eval_rev1.spi file.

You may create and save your own command for specific purposes.

• Gen4 devices need a WD toggle on bit D11 to stay in normal mode. The interface board

KITUSBSPIDGLEVME is not able to generate and take into account WD bit status. Therefore, when doing

your own sequence, you may take this into account, and use the "Send Continuously" button.
