Smart or protected switches are MOSFETs with integrated logic which allows protection and diagnostic functionalities. Examples of typical loads could be e.g. lamps, heating systems, solenoids, motors, electronic components (ECU). This haven been part of product line of Infineon on IPM module with larger Size and Capacity. The module in much compact size and strong enough for application below 100W. Here is the list in this Road test.
In this road test , the three Protected Switch Shield shall be tested. Especially the function with Capacitor as power source. This brings more challenge like over current and unbalance current load.The arduino uno and XMC1100 Boot Kit both can provide control signals to Shield Board. Therefore, Arduino Uno is used as main development platform in this Roadtest. Same code can be used for XMC1100 Boot Kit if follow the instructions on https://github.com/Infineon/XMC-for-Arduino .

The shield with Infineon’s high-side switch Power PROFET™ BTS50010-1TAD can be controlled by a programmable microcontroller, e.g. XMC1100 Boot Kit, a 32-bit ARM® powered MCU from Infineon. For stand-alone mode, BTS50010 1TAD can be commanded ON/OFF by connecting pin P0.3 to 5 V (P2.10) or 12 V (VBat). The IS signal of BTS50010 is monitored by the on-board circuitry, indicating operation mode of BTS50010 on LED3 (green for normal mode) and LED4 (red for FAULT mode, such as overtemperature or short circuit to GND).
Low-Side Switch Shield with BTF3050TE for Arduino
The Low-Side Switch Shield from Infineon consists out of three BTF3050TE low-side switches of the HITFET™+ family providing three independent power channels that can be controlled via the input pins. The shield is compatible with microcontroller boards using the Arduino form factor for example the corresponding ARM® powered XMC™ microcontroller kits from Infineon and supports fast and easy prototyping of applications with BTF3050TE. With a nominal load current of 3 A the BTF3050TE is able to drive resistive, inductive and capacitive loads. Furthermore the smart low-side switch provides diagnosis and protection features (e.g. overtemperature, overcurrent).
XMC1100 Boot Kit
The XMC1100 Boot Kit is an Arduino compatible base board using Infineon’s XMC1100 ARM Cortex – M0 32-bit Microcontroller. It has two rows of pin headers which fully compatible with Arduino shield. Hence, user can buy various Arduino shield boards off-the-shelf to test the capabilities of XMC1100 Microcontroller. It is equipped with the following features:
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
