MDC3105
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.
