Demoboard BTF3xxxEJ User Manual
1 Getting Started
1.1 BTF3xxxEJ Shield overview
The 12V low-side switch demoboard with one BTF3xxxEJ from Infineon Technologies is a flexible evaluation
board dedicated to drive all kinds of loads. This demoboard is compatible with Arduino UNO shield and
Infineon XMC1100.
The demoboard can be controlled either with the general logic I/O-ports of a microcontroller or with a PWM.
It includes typical schematic to control the BTF3xxxEJ. This shield offers a quick evaluation of the product, the
“Status” latch functionality, the “SRP” functionality, the “ENABLE” functionality, the “I_lim_trigger”
functionality, the turn-ON in inverse current condition functionality, and all protections, e.g. “Over temperature
shut down” and “Dynamic temperature protection”.
WARNING:Please refer to BTFxxxEJ Datasheet for details on functionalities and parameters values. This user
manual does not replace the datasheet and user must be aware of limitations before turning on any supply.
The demoboard can be easily connected to any Arduino UNO board or Infineon XMC1100 via headers.
Code and graphic interface is available for Arduino UNO.
No code/interface is available for XMC1100, but XMC1100 can be easily programmed through Arduino IDE:
please check the following link for details: https://github.com/Infineon/XMC-for-Arduino
1.2 Key features
oDemoboard is able to provide continuous current load (30V- 15A) between V_OUT and GND.
oA green LED will turn ON when logic supply voltage is connected and ON.
oOutput voltage, Input logic, Status and Logic voltage can be measured externaly with test points.
oInput logic, Status can be monitored with the Arduino Interface.
1.3 Demoboard package contents
In the zip package must be the following:

2 Demoboard configuration
oIf an Arduino board is used, configuration needs to be set in the software. Please refer to Error!
Reference source not found. Error! Reference source not found. command, where
parameters of used demoboard can be selected.
2.1 Status pin connection
oBTF3xxxEJ has STATUS pin pulled-up to Vdd to allow fault monitoring, and fault reset
oStatus pin can be reset via the GUI interface.
oIf no diagnosis is needed, the Status pin can be connected to the Input pin via permanent
pressure on S2 button. This will light LED L1.
2.2 Enable pin connection
oBTF3xxxEJ has an ENABLE pin. When switched off, it guarantees a very low leakage on drain and
Vdd. It also reset status and I_lim_trigger
oYou can ENABLE (pull-up to Vdd) or disable the device (pin open) with a jumper.
oEnable can also be turned ON/OFF via the GUI interface.
2.3 Slew Rate pin configuration
oUse jumper to choose SRP resistor value from GND to 58kΩ. Values of SMD resistors on the
boards are the same that are characterized in the Datasheet (GND, 5.8kΩ, 58kΩ, open). Use
jumper accordingly.
3 Software utilisation
oSoftware “Demoboard_Aiko_Universal.exe” is a GUI for Windows OS, used with the Arduino UNO
board with the dedicated code “Demoboard_Aiko_Universal.ino”.
3.1 Installation
oUser has to install the Arduino IDE software to allow communication between computer and
Arduino board.
oOnce the program is installed, connect the Arduino shield. Double-click the
“Demoboard_Aiko_Universal.ino” Arduino code and upload it.
RSRP=5.8kΩ
RSRP=58kΩ
RSRP=GND

Demoboard BTF3xxxEJ User Manual
oWhen the code is correctly uploaded/ installed, the user can plug the demoboard on the
Arduino shield. The green LED must turn on, meaning that BTF3xxxEJ logic is supplied.
oA message ‘Done uploading’ is displayed in Arduino IDE.
oThen, launch “Demoboard_aiko_Universal.exe”.
Click on “Ports” to select the right communication port on your Arduino board.
Click on “Start” to start the system.
If it’s not working, check your port name.
Port name is usually called “COM X”, where “X” is a number.
If installation is done and operational, a green box is displayed above the Start and Stop
buttons in the GUI Overview page. A red box shows a malfunction communication, in
which case close the program, upload again and start again.
oWhen user wants to turn OFF the application, user has to click on “Stop” before closing the
windows (none application can be shut down before closing the communication with the
Arduino board).
3.2 Features
Monitoring Panel3.2.1
oBTF3xxxEJ color control has three possible states: . FA indicates STATUS is latched.
oIf BTF3xxxEJ operates normally, Vstatus should appear in green.
oIf BTF3xxxEJ is latched, Vstatus appears in red. Status needs to be reset by pressing S2 or via
Alternative command page.
Control Panel3.2.2
oButtons ON and OFF allow user to switch ON and OFF BTF3xxxEJ in continuous mode.

oButton “Pulse” creates a manageable pulse on BTF3xxxEJ.
User can create a pulse with period control
Ending Action defines if the device is left ON or OFF after the pulses.
Duration of ON pulse is adjusted with “Positive width” value
Duration of OFF pulse is adjusted with “Negative width” value
oButton PWM allows user to manage dutycyle and frequency.
Alternative Command3.2.3
oButton Reset Status reset the Status and the function I_lim trigger
oButton Reset Trigger reset the function I_lim trigger only
oButton ENABLE switches ON or OFF the enable pin.
