Infineon Technologies SHIELDBTF3050TE Low-Side Switch Shield

Infineon Technologies SHIELDBTF3050TE Low-Side Switch Shield is a demonstration and development platform for the BTF3050TE HITFET™ Smart Low-Side Power Switch. The SHIELDBTF3050TE Shield features three HITFET™ BTF3050TE Low-Side Power Switches. The SHIELDBTF3050TE can be used in stand-alone and microcontroller (MCU) mode and can be controlled by Arduino-compatible MCU boards. The shield is easy to use and fully configurable for different kinds of loads.

The board supports fast and easy prototyping of applications with BTF3050TE. The BTF3050TE is a 50mΩ high integrated single channel low-side switch. The switch is able to drive resistive, inductive and capacitive loads with a nominal load current of 3A.

The power transistor itself is a built in N-channel power MOSFET. The whole device is monolithically integrated with the power MOSFET, driver and protection blocks all in one package.

The smart low-side switch provides diagnosis and protection features (e.g. overtemperature, overcurrent). BTF3050TE is qualified and optimized for 12V automotive and industrial applications.
