The NUD3112DMT1G is an Inductive Load Driver used to switch inductive loads such as relays, 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.
Provides a robust driver interface between DC relay coil and sensitive logic circuits
Optimized to switch relays of 12V rail
Capable of driving relay coils rated up to 6W at 12V
Internal Zener eliminates the need of free-wheeling diode
Internal Zener clamp routes induced current to ground for quieter systems operation
