ON Semiconductor NUD3112LT1G

Description
The NUD3112 Integrated Relay, Inductive Load Driver is a device used to switch inductive loads such as relays, solenoids, incandescent lamps, and small DC motors without the need for a free-wheeling diode. It integrates all necessary items such as the MOSFET switch, ESD protection, and Zener clamps. It accepts logic level inputs, allowing it to be driven by a wide 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 for a free-wheeling diode
Internal Zener clamp routes induced current to ground for quieter systems operation
Low VDS(ON) reduces system current drain
SZ prefix for automotive and other applications requiring unique site and control change requirements; AEC-Q101 qualified and PPAP capable

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
