ON Semiconductor MDC3105DMT1G

Description
The MDC3105 is an integrated relay and inductive load driver designed to replace multiple discrete components. It is available in a compact SOT-23 package and can switch inductive loads up to 2.5W at 5.0V.

Features
Robust driver interface between DC relay coil and logic circuits
Optimized for switching relays from 3.0V to 5.0V
Low input drive current and good back-to-front transient isolation
Internal Zener eliminates the need for a free-wheeling diode
Internal Zener clamp routes induced current to ground for quieter operation
Guaranteed off state with no input connection
Supports large systems with minimal off-state leakage
ESD resistant in accordance with Class 1C Human Body Model
Low saturation voltage reduces system current drain

Applications
Telecom: Line cards, modems, answering machines, FAX machines, feature phone electronic hook switch
Computer and office: Photocopiers, printers, desktop computers
Consumer: TVs and 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: 5.0V driven relays, motor controls, power latches, lamp drivers
