MDC3105LT1
Integrated Relay,
Inductive Load Driver
This device is intended to replace an array of three to six discrete
components with an integrated SMT part. It is available in a SOT−23
package. 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 & 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 2000 V Human Body Model
Low Sat Voltage Reduces System Current Drain by Allowing Use of
Higher Resistance Relay Coils
Applications Include:
Telecom: Line Cards, Modems, Answering Machines, FAX
Machines, Feature Phone Electronic Hook Switch
Computer & Office: Photocopiers, Printers, Desktop Computers
Consumer: TVs & VCRs, Stereo Receivers, CD Players, Cassette
Recorders, TV Set Top Boxes
Industrial: Small Appliances, White Goods, Security Systems,
Automated Test Equipment, Garage Door Openers
Automotive: 5.0 V Driven Relays, Motor Controls, Power Latches,
Lamp Drivers
