Infineon – PROFET 24V Protected Switch Shield with Arduino


Infineon Logo
Infineon’s PROFET +24V family of protected high side switches (BTT6xxx) drive resistive, capacitive, and inductive loads. For example – commercial, agricultural, automotive bulbs, valves, motors, relays, capacitors, and LEDs. Using the 24V protected switch shield with Arduino enables fast, cost effective prototyping and evaluation of pin-to-pin compatible PROFET +24V devices.

The shield is equipped with three protected high side power switches out of the PROFET + 24V family (2x BTT6030-2EKA, 1x BTT6020-1EKA). It can be controlled either by an Arduino board (e.g. Arduino Uno, Arduino Due) or the ARM® powered Infineon XMCTM microcontroller kits using the Arduino form factor.

The power switches are controlled via the INx (input) pins. The PROFET + 24V devices also provide a sense current at the IS pin, which can be enabled via the DEN (Diagnosis ENable) pin. For the two channel devices the sensed channel is selected via the DSEL (Diagnosis SELect) pin. For each device the sense signal (IS) is connected to its own ADC channel of the microcontroller.
