Arduino-compatible 24V protected-FET switch shield, in distribution

October 31, 2016 // By Graham Prophet
Distributor Mouser Electronics has the Protected Switch Shield with PROFET 24V for Arduino, from Infineon Technologies. The 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 allows engineers to prototype and evaluate designs using Infineon’s PROFET 24V family of protected MOSFETS. The shield is equipped with three protected high-side power MOSFETs — two BTT6030-2EKA and one BTT6020-1EKA — which offer a total of five 24V channels, each with a nominal current of 4A to 5A. PROFET intelligent power switches consist of DMOS power transistor and CMOS logic circuitry for complete built-in protection. The devices offer protection against overload, overvoltage, short-circuit, excessive temperature, loss of ground, power supply loss, and electrostatic discharge (ESD). The PROFET devices are also capable of protecting against dynamic overvoltage such as load dump and inductive load turn-off.


The shield runs off 8V – 36V nominal input voltage and provides a driver circuit with logic level inputs and load diagnosis with current sense capability. The PROFET 24V devices are designed to drive resistive, capacitive, and inductive loads such as automotive bulbs, valves, and supply switches for motors using PWM (up to 400 Hz) or DC.
