24 V Protected Switch Shield

Infineon's 24 V protected switch shield enables fast prototyping and inexpensive evaluation of the pin-to-pin compatible PROFET™+ 24 V devices

Infineon's 24 V protected switch shield is a power switch evaluation board compatible with Arduino microcontroller boards and with Infineon’s XMC™ microcontroller kits using the Arduino form factor. The shield is equipped with three PROtected high-side power MOSFETs out of the PROFET+ 24 V family, two BTT60302EKAXUMA1 and one BTT60201EKAXUMA1, offering five 24 V channels in total. The PROFET™+ 24 V (PROtected FET) is a 24 V high-side switch that incorporates protection against overload, overvoltage, short circuit, excessive temperature, loss of ground, power supply loss, and ESD.

The PROFET+ 24 V protected high-side switches (BTT60302EKAXUMA1 and BTT60201EKAXUMA1) drive resistive and capacitive, as well as inductive loads such as truck bulbs, car bulbs, valves, motors, relays, capacitors, and LEDs. The power switches are controlled via the INx (input) pins. The PROFET+ 24 V 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 an own ADC channel of the microcontroller.
