Demoboard BTT3018EJ User Manual
1 Getting Started
1.1 BTT3018EJ Shield overview
The 24V low-side switch demoboard with one BTT3018EJ 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 BTT3018EJ. This shield offers a quick evaluation of the product, the
“Status” latch functionality, the “SRP” functionality, and all protections, e.g. “Over temperature shut down”.
WARNING:Please refer to BTT3018EJ 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
o Demoboard is able to provide continuous current load (36V- 20A) between V_OUT and GND.
o A green LED will turn ON when logic supply voltage is connected and ON.
o Output voltage, Input logic, Status and SRP can be measured externaly with test points.
o Output voltage, Input logic, Status can be monitored with the Arduino Interface.
1.3 Demoboard package contents
In the zip package must be the following:
o Demoboard_BTT3018EJ_User_Manual_Vx.x
o Demoboard_BTT3018EJ.exe

2 Demoboard configuration
o If an Arduino board is used, configuration needs to be set in the software. Please refer to 3.2.3
Demoboard configuration panel.
2.1 Status pin connection
o BTT3018EJ can be controlled with pin pulled-up to Vdd to allow fault monitoring.
o If no diagnosis is needed, the Status pin can be connected to the Input pin
o Use Jumper to choose configuration.
2.2 Slew Rate pin configuration
o Use jumper to choose SRP resistor value from GND to 160kΩ. Values of SMD resistors on the
boards are the same that are characterized in the Datasheet (GND, 2.2kΩ, 5.8kΩ, 10kΩ, 58kΩ,
160kΩ). Use jumper accordingly.
3 Software utilisation
o Software “Demoboard_BTT3018EJ.exe” is a GUI for Windows OS, used with the Arduino UNO
board with the dedicated code “Demoboard_BTT3018EJ.ino”.
3.1 Installation
o User has to install the Arduino IDE software to allow communication between computer and
Arduino board.
o Once the program is installed, connect the Arduino shield. Double-click the
“Demoboard_BTT3018EJ.ino” Arduino code and upload it.
o When the code is correctly uploaded/ installed, the user can plug the demoboard on the Arduino
shield. The green LED must turn on, meaning that BTT3018EJ logic is supplied.
o Then, launch “Demoboard_BTT3018EJ.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, user can see text transmitted by the Arduino board
below the port selector.
o When 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).
 WARNING: when application is stopped, it has to be shut down then restarted again.
3.2 Features
Monitoring Panel
o BTT3018EJ color control has three possible states: . If FA, please stop and close the
program, then restart it again.
o If BTT3018EJ operates normally, Vstatus should appear in green.
o If BTT3018EJ is latched, status appears in red. Status needs to be reset by 5V pull-up if not
connected to Input.
Control Panel
o Button ON and OFF allow user to switch ON and OFF BTT3018EJ in continuous mode.
o Button “Pulse” creates a manageable pulse on each BTT3018EJ.
 User can create a pulse with period control
 The timing can be from 1ms to 1000s in logarithmic mode.
o Button PWM allows user to manage dutycyle and frequency.

Demoboard configuration panel
o To use the Vout measure, user needs to go to “demoboard configuration panel” to set the
monitoring resistors. It is a simple voltage divider that should be designed to protect the Arduino
microprocessor in current and voltage. Resistors can be connected in the “Tulip” connectors
without soldering. Examples of values:
 Rmonitor1 = 10kΩ
 Rmonitor2 = 1kΩ
o Vstatus can be in the pull up mode or can be connected to Vin, user needs to go to “demoboard
configuration panel” to set the right statement.
