NUD3112This device is 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.
Features
• Provides a Robust Driver Interface Between D.C. Relay Coil and
Sensitive Logic Circuits
• Optimized to Switch Relays of 12 V Rail
• Capable of Driving Relay Coils Rated up to 6.0 W at 12 V
• Internal Zener Eliminates the Need of Free−Wheeling Diode
• Internal Zener Clamp Routes Induced Current to Ground for Quieter
Systems Operation
• Low VDS(ON) Reduces System Current Drain
• Pb−Free Package is Available
