MDC3105LT1G Description
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 for a free?wheeling diode.
MDC3105LT1G Features
Provides a Robust Driver Interface between DC Relay Coil and
Sensitive Logic Circuits
Optimized to Switch Relays from a 3.0 V to 5.0 V Rail
Capable of Driving Relay Coils Rated up to 2.5 W at 5.0 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
Pb?Free Packages are Available
