Protected Switch Shield with PROFET™+ 24V for Arduino
1 24V Protected Switch Shield introduction
1.1 24V Protected Switch Shield overview
The 24V Protected Switch Shield adds advanced driving and diagnostic of generic loads to the Arduino projects.
The shield can be controlled with the general logic IO-Ports of a microcontroller. Either an Arduino Uno R3, the
XMC1100 Boot Kit or the more powerful XMC4700 Relax Kit and XMC4800 Relax Kit from Infineon can be used as
the master.
On board of the 24V Protected Switch Shield are two BTT6030-2EKA and one BTT6020-1EKA PROFETTM+24V.
Each of the BTT6030-2EKA features two 32 mΩ Smart high-side power switch-channels, whereas the BTT6020-
1EKA features a single 20 mΩ channel. In total the shield provides five Smart High-Side Power Switch Channels.
Each is built by a vertical N-channel power MOSFET with charge pump.
Due to the integrated charge pump the channels can be controlled by standard digital IOs (3.3 V and 5 V
supported).
The 24V Protected Switch Shield can be easily connected to any Arduino compatible board like the XMC1100
Boot Kit via headers.

1.2 Key features
The 24V Protected Switch Shield has the following features:
An Arduino Uno R3, XMC1100 Boot Kit, or similar board connected to the shield can control the five power
channels via the general IO pins.
Drives resistive, capacitive and inductive loads with PWM or in DC (eg. truck bulbs, car bulbs, valves, motors,
relays, capacitors, LEDs…)

1.3 Block diagram of an automotive light control
Figure 3 depicts the Block diagram of the 24V Protected Switch shield. The IS pins of all 3 devices used for the
current sensing could be connected to a single analog digital converter at the µC. But for simplification each IS
pin is connected to an own analog digital converter. The microcontroller and its power supply are not part of the
shield.

2.3 Pin assignment
To use the 24V Protected Switch Shield the necessary control signals can be applied directly at the connectors.
There is no need to use a microcontroller compatible with Arduino or XMC 1100 Boot Kit to get the 24V
Protected Switch Shield into an application. The control pins are logic level inputs which can be driven by any
other microcontroller or with logic level signals. Besides the supply voltage Vbat has to be provided to the Vbat
connector. Figure 8 shows the pinout/connectors of the 24V Protected Switch Shield.

Protected Switch Shield with PROFET™+ 24V for Arduino
5 Getting Started
5.1 Target applications
The application targeted by the BT60xx devices is driving lamps in 24V Trucks and Transportation systems.
Besides lamps any other inductive, resistive and capacitive load within the electrical characteristics of the
PROFET™+24V can be driven by the BT60xx. In the 24V Protected Switch Shield two BTT6030-2EKA and one
BTT6020-1EKA are used. Each channel of the BTT6030 is capable of driving up to 4 A (both channels active). The
single channel of the BTT6020 is capable of driving up to 7 A. The limited thermal performance of the Shield PCB
limits the recommended maximum current to 5 A.
5.2 Typical target applications
With the 24V Protected Switch Shield up to five 24 V loads can be driven. The switches are controlled via the INx
(Input x) pins. The BTT60xx also provide a sense current at the IS pin. The Shield provides a fast and easy access
to 24 V load switching up to 1 x 5 A + 4 x 4 A.
5.2.1 Getting started: Shield
Choose loads compatible within the electrical characteristics in the Datasheets of the BTT60xx
o E.g. 1 x 70 W 24 V lamp and 4 x 21 W 24 V lamps (Truck bulbs)
Choose a DC adapter. The nominal input of the Shield is 8 – 36 V DC. Maximum Voltage is 48 V
Connect the Shield to Arduino Uno R3 or XMC 1100 Boot Kit.
Connect power supply (5 V) to the Arduino Uno R3 or XMC 1100 Boot Kit (Micro USB). For the XMC Boot
Kit a standard mobile phone charger can be used.
Program the controller board with the lamp switching software (see 5.2.2).
Connect the Out connectors of the shield
o 70 W to OUT0_2
o 21 W to Out0_1, Out 1_1, Out 0_0 and Out 1_1
Connect the DC adapter to the Power Shield (Vbat, GND).

Or during runtime using the API. To get information about the API right click on the APP and select APP Help:
The Help will open in a new Window. Selecting Apps Methods shows a documentation of all available
methods for this type of APP.
The Software does not only drive the loads in PWM. It also measures continuously the Sense signal and
calculates out of it the load current during the high phase of the PWM period. The calculated currents are then
stored in global variables enabling the user to process the values in his code e.g. for a protection strategy or to
calculate the power consumption. For more details on how the load current is calculated check the
documentation in the code. The provided software is an example and is not a reference software.
