The Low-Side Switch Shield from Infineon consists out of threeBTF3050TElow-side switches of the HITFET™+ family providing three independent power channels that can be controlled via the input pins. The shield is compatible with microcontroller boards using the Arduino form factor for example the corresponding ARM® powered XMC™ microcontroller kits from Infineon and supports fast and easy prototyping of applications with BTF3050TE. The BTF3050TE is a 50 mΩ high integrated single channel low-side switch and able to drive resistive, inductive and capacitive loads with a nominal load current of 3 A. The power transistor itself is a built in N-channel power MOSFET. The whole device is monolithically integrated. This means that the power MOSFET, the driver and protection blocks are integrated in one package. Furthermore the smart low-side switch provides diagnosis and protection features (e.g. overtemperature, overcurrent). BTF3050TE is qualified and optimized for 12 V automotive and industrial applications.
