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.

• 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
