NUD3105D Datasheet, PDF (1/8 Pages) ON Semiconductor – Integrated Relay, Inductive Load Driver

NUD3105D
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 from 3.0 V to 5.0 V Rail
• Capable of Driving Relay Coils Rated up to 2.5 W at 5.0 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
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
• Automotive: 5.0 V Driven Relays, Motor Controls, Power Latches,
Lamp Drivers
