NUD3112 Datasheet, PDF (1/8 Pages) ON Semiconductor – Integrated Relay, Inductive Load Driver

NUD3112
Integrated Relay,
Inductive Load Driver
This 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 V_DS(ON) Reduces System Current Drain
• Pb−Free Package is Available
Typical Applications
• Telecom: Line Cards, Modems, Answering Machines, FAX
• Computers and Office: Photocopiers, Printers, Desktop Computers
• Consumer: TVs and VCRs, Stereo Receivers, CD Players, Cassette
Recorders
• Industrial: Small Appliances, Security Systems, Automated Test
Equipment, Garage Door Openers
