NUD3112中文资料继电器驱动器，12V数据手册ONSEMI规格书

描述 Description

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.

特性 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

应用 Application

• Telecom: Line Cards, Modems, Answering Machines, FAX
• Consumer: TVs and VCRs, Stereo Receivers, CD Players, Cassette
• Industrial:Small Appliances, Security Systems, Automated Test Equipment, Garage Door Openers
• Computers and Office: Photocopiers, Printers, Desktop Computers
