The project presented here enables users to switch all kinds of resistive, inductive and capacitive loads, limited by clamping energy (EAS) and maximum current requirement. The user may interface 2 x inductive, resistive, and capacitive loads such as solenoid, dc motor, high current contact switch, high current relay, LEDs, lamps, and piezo etc. The project is most suitable for inductive loads as well as loads with inrush current. The project has been designed using BTF3050TE IC which is a 50 mΩ single-channel Smart Low-Side Power Switch in a PG-TO252-5 package providing embedded protective functions. The power transistor is built by a N-channel vertical power MOSFET. The device is monolithically integrated. The BTF3050TE is automotive qualified and is optimized for 12V automotive and industrial applications. Two loads can be controlled using Arduino UNO. IC has a thermal-restart function. The device will turn on again, if input is still high, after the measured temperature has dropped below the thermal hysteresis.
