Relay Driver, 5.0 V, Single

Key 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 VDS(on) Reduces System Current Drain

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.
