Relay Driver, 5.0 V

Key Features

• Provides a Robust Driver Interface between D.C. Relay Coil and Sensitive Logic Circuits

• Optimized to Switch Relays from a 3 V to 5 V Rail

• Capable of Driving Relay Coils Rated up to 2.5 W at 5 V

• Features Low Input Drive Current and Good Back-to-Front Transient Isolation

• Internal Zener Eliminates Need for Free-Wheeling Diode

• Internal Zener Clamp Routes Induced Current to Ground for Quieter System Operation

• Guaranteed Off State with no Input Connection

• Supports Large Systems with Minimal Off-State Leakage

• ESD Resistant in Accordance with the Class 1C Human Body Model

• Low Sat Voltage Reduces System Current Drain by Allowing Use of Higher Resistance Relay Coils

Description

This Relay Driver is intended to replace an array of three to six discrete components with an integrated SMT part. It can be used to switch 3 to 6 Vdc inductive loads such as relays, solenoids, incandescent lamps and small DC motors without the need of a free-wheeling diode.
