NUD3105D

Integrated Relay,

Inductive Load Driver

solenoids incandescent lamps, and small DC motors without the need

of a free−wheeling diode. The device integrates all necessary items

such as the MOSFET switch, ESD protection, and Zener clamps. It

accepts logic level inputs thus allowing it to be driven by a large

variety of devices including logic gates, inverters, and

microcontrollers.
