NUD3105DMT1G is a kind of integrated relay, inductive load driver integrating all necessary items, which is manufactured by ON Semiconductor to switch inductive loads requiring no free?wheeling diode due to its internal Zener such as relays, solenoids incandescent lamps, and small DC motors. Based on the logic level, it can be driven by a large variety of devices, such as logic gates, inverters, and microcontrollers.
