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. TM On board of the 24V Protected Switch Shield are two BTT6030-2EKA and one BTT6020-1EKA PROFET +24V. Each of the BTT6030-2EKA features two 32 m Smart high-side power switch-channels, whereas the BTT60201EKA features a single 20 m 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. Figure 1 1.2 24V Protected Switch Shield photo 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.

Besides lamps any other inductive, resistive and capacitive load within the electrical characteristics of the PROFETTM+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).

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.
