Product Summary

The MDC3105LT1G is an integrated relay, inductive load driver. The MDC3105LT1G is intended to replace an array of three to six discrete components with an integrated SMT part. The MDC3105LT1G is available in a SOT-23 package. The MDC3105LT1G 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.
