Infineon – 24V Protected Switch Shield with PROFETsTM for Ardunio

pg5_Infineon_image2Infineon Logo             NPI_LOGO

Infineon’s PROFET +24V family of protected high side switches (BTT6xxx) drive resistive, capacitive, and inductive loads. For example – automotive bulbs, valves, motors, relays, capacitors, and LEDs. Using the 24V protected switch shield for 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 MOSFETs 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.

The BTT6030-2EKA and BTT6020-1EKA are integrated high side power switches and are a part of the PROFET + 24V family. The power transistor is built by an N-channel vertical power MOSFET with charge pump in one package (DSO-14). To block reverse current on the board, an IPD50P04P4L-11 is used.
