NUD3105D数据手册集成电路（IC）的配电开关负载驱动器规格书PDF

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 from 3.0 V to 5.0 V Rail
• Capable of Driving Relay Coils rated up to 2.5 W at5.0 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 and FAX
• Computers and Office:Photocopiers, Printers, and Desktop Computers
• Consumer:TVs and VCRs, Stereo Receivers, CD Players, Cassette Recorders
• Industrial:Small Appliances, Sercurity Systems, Automated Test Equipment, Garage Door Openers
• Automotive:5.0V Driven Relays, Motor Controls, Power Latches, and Lamp Drivers
